      Like many commenters here, I was also an early backer and paid ages ago, still no communication about delivery to the forgotten lands of the Southern Hemisphere. It will be a miracle if the wheel ever arrives - it was supposed to arrive May 2014. I've written off the investment, and will probably go and buy another bike in the near future which can be reliably serviced and maintained by a retailer. Wiser and poorer.

    2. Creator Melissa Gatlin on June 22

      Has anyone received the phone holder ... not the wheel, but the combo light and phone holder?

    3. Creator Ron And Catherine Reed on June 18

      The lack of update via email, etc. has been bad. I am now buying another product.

    4. Creator Phillip Dean on June 18

      I found messaging them on Facebook gets a faster response. Not a good response, but faster. I pinged them with a request for information on my wheel delivery since I wasn't part of the first shipment to North America. I got a response (yay) but all they said was "Your Smart Wheel will be shipped in July." (boo).

    5. Creator Tod Harrick on June 18

      Yup. 2 years and still waitin' for that wheel. Dum, de dum de dum.

    6. Creator JVVH on June 18

      Still waiting for my wheel and light.

    7. Creator Tim W. on June 8

      I've not looked at the comments in a while fearing I would only see a confirmation of my suspicion. I am gone to request a refund. The customer service and updates are poor. I have grown tired of waiting.

    8. Creator James Dichter on May 30

      I think we are spinning wheels thinking Flykly is capable or interested in customer service or creating a worthwhile product,

      A simple thing like shipping a box from Boston to NY has now become a frustrating strange experience.
      Flykly acknowledged that my wheel was not initialized correctly and would need to be shipped to NY. Simple I thought living in Boston. But it is going on one month now and still waiting to receive return Shipping Label. (Apparently UPS is sending my label by mail from Europe)

      The comments and experiences from users clearly show what we got was not the product promised. Importantly there looks to be a number of potentially dangerous problems -- overheating in charging, braking, turning....

      There is a legal One Year Warranty on the Smart Wheel. The current Smart Wheel failures should be covered by this Warranty.

      Do you think we need to go the legal route?

    9. Creator Holly Ellingson on May 28

      Still, I am waiting for any response or delivery of the light I paid for. I am very frustrated. I was initially very excited and proud to be a part of this campaign, and now, two years later, I'm neither excited nor proud. I'm skeptical and disgusted. I keep reading updates that say "nearly every" part has been delivered, yet I've not seen mine. Still. After two years. How are they not facing legal repercussions for this nonsense? From reading the comments, it seems that my situation is far from unique. I'm certainly glad I didn't invest in the wheel itself!

    10. Creator T Phelan on May 28

      Great you raised almost 3/4 of a million dollars, great you're in 50 countries. :)

      Not great I was one of the first backers almost 2 years ago and still have yet to receive my two wheels. :(

    11. Creator Fact Multimedia Design on May 28

      I posted this comment a while ago till this date no proper reply, i also replied kickstarter and they mailed back stating:" flykly was a very succesfull project on kickstarter with lots of happy backers for problems you should contact the project founders"....

      well i don't support this and made me come to this date (giving both kickstarter to reply adequately) too:

      - open a website flyklyproblems.com
      - post my review on every website that has left reviews (which btw seem to be bullocks because the wheel was in complete testing fase)
      - sell my wheel online

      I feel completly screwed over....

      Hello everyone except FlyKly (callled FK from now on) as they will not respond.....
      I have received the "smartwheel" about two months ago, living in Amsterdam 3th floor..... i started mounting immediately....
      When installing, configuring and using i encountered the following issues/problems:
      1. The phone holder is not included in the original shipment i realized later and got answer of FK it will be sent later....
      2. the rubber wheel is mounted from the factory the wrong way (resolution FK you or a bike shop has to just swap the rubber wheel)
      3. There are no chain tensioners provided and the bolts are to big for my city bike so the chain will be loose (resolution FK let a bike shop or you remove a shackle from the chain)
      4. Bluetooth will not connect when sitting on the bike (resolution is hold the phone close to the wheel and setup the wheel). It took me over 30km before i got it connected after its connected you still have to connect from within the FlyKly app..... this will repeatedly says there is no bluetooth connection....So you have to switch back again to BT settings connect etc etc. Once connected you can setup the wheel after its setup the settings are stored in the wheel and the wheel will start assisting you based on the choosen settings.... woop woop ureka!
      5. Because in holland we have city bikes with a brake in the rear wheel, when reversing your paddle you use the full brake. The FK wheel does have a braking assist and i have it working but its not as instant as the conventional brake. (solution FK is to mount a brake on your front wheel as extra safety)
      6. When the wheel is empty of power you have no brake at all (if you have not followed FK's advice) (FK response was no worries the wheel is smart enough to remember your settings) well its not that smart....
      7. When the wheel is empty there is no other solution then carrying up my 20 kilo citybike up three stairs and put it to charger..... This in my opinion could have been resolved easily by adding a setting in the app.....Turn of power consumption recharge wheel by biking....
      8. Now the fun part begins when you finally have things working, the wheel is setup, its charged and your biking like a loony (yes you are this is one of the few positive things, the wheel 94% of the time does help you pretty well). And when you think let's try and change some settings (hopefully bluetooth is still connected and the app too)...... you will try to adjust the sliders you will get a notification "You cannot adjust the settings while biking" So you stop to adjust.... then when you try to adjust it, it says sorry connection lost.......believe me this is where it becomes really frustrating ....
      9. FlyKly asked me to sent them some pictures of me being happy on the bike, i answered well at the moment im just frustrated and trying to sort out the issues..... instead of receiving an answer like we are here to help you lets resolve this... i did not hear anything .... yesterday i posted a message on facebook that im actually pretty pissed.....
      10. One of my friends own a bikestore Kaptein while taking the wheel apart the mechanic (which i know is good) dismantled the sprockets to have a look..... the sprocket used is not locked by a in bike world called lockbolt. This can and will most likely cause problems in the future (my own opinion)....
      10a. you can order a lockbolt and resolve problem 9b after this you cannot remove the sprocket anymore and replace it when needed, your wheel becomes trash
      10b. use the sprocket without a lockbolt try to tighten it as much as possible buttt in the future the sprocket can become loose when biking forward it will have a backlash of about 2-3 mm same problem paddling backward
      11. The valve is American, Europeans need to buy a converter so you can inflate your wheel
      Problem in my opinion is good words about they did testdrives (which i believe im an uninformed participator) in some cites which where very succesfull. Well i can tell you one thing if this was tested it was tested completely wrong because 2,4,6,7,8,9, 10, 11 for sure and maybe 3 could have been resolved..... Im just curious is there anyone active here that has tested the wheel in person?
      You know if they would have said to me, please test the wheel (for free) and give us feedback, i would have been a happy camper. But i paid a substantial amount of money for a product that is far from finished and the biggest issues in my opinion are.
      - (4) the bluetooth (i BT believe the hardware in the wheel is not of god quality)
      - (10) the used sprocket and mounting of it
      - (6) no recharge option by normal biking without using assist
      - the lack of proper communication of the project founders....because i believe this is the only way they can save the project as trust for me is completely gone.
      It all sounded so nice when it started.......

    12. Creator Drew Tennimon on May 27

      looks like i am getting my sondors ebike b4 this, so anyone want to buy mine whenever it finally ships?

    13. Creator Nicholas Wang on May 21

      @JackBurnett. I'm in Chicago and have also not received my wheel. Not sure which backer I was, but I went in on the first day, Oct 16th. I am a "$550 early bird" backer.

      I contacted FlyKly via email last month and was told that I would be in the second batch - to "go out in July/August".

      With any luck, they'll have worked through some of the issues enumerated below by then.

    14. Creator theadrew on May 18

      @JackBurnett yup. I'm in chicago and have a wheel. I was backer #52 so I assume that's how I got in the first batch.

    15. Creator Jack Burnett on May 14

      Has anyone near Chicago received their wheel yet? I figure I will not receive it before winter, but you never know. Thanks.

    16. Creator James Dichter on May 14

      Thanks for your feedback on connection problem.
      The Flykly folks informed me that my problem in establishing a Bluetooth connection is due to my Smart Wheel not being fully configured. They said I would need to send wheel to NY to be fixed. They acknowledged it was their problem but after many emails are still not providing details on how to ship it to them. Almost 2 weeks and somehow they are not capable of arranging shipping a wheel from Boston to New York! Very Frustrating. Has anyone had luck with getting proper Customer Service.

    17. Creator Peter on May 12

      Had my wheel for about a month now. Figured I could share my thoughts on it.

      The bad:
      - Horrible bluetooth connection. Can only connect to the wheel if very close (About 30cm max). Kind of defeats the purpose and fails to deliver on what was promised. It can't be used as advertised.
      - Cumbersome connection process. You need to manually connect to the wheel in BT settings each time then switch to the app and connect there. No auto connect.
      Sometimes after doing the whole connection process it instantly drops connection and then you cant reconnect.
      - Accelerates while steering the bike, as the small cog follows the hub sometimes. When you least expect it, it starts to accelerate! Its both embarrassing and dangerous!
      - App is very poorly made with lots of bugs and bad user experience.
      - Battery indicator unreliable and not very accurate. Example: Showing 30% and it ran out after 5 mins. From full charge going 10km it can show 99% etc. You can't rely it to take you home with below 40% power.
      - Battery runs out faster than expected.
      - Poor quality in phone holder, can't possible hold its own weight + phone.
      - Quite heavy, didn't really realize what a pain it would be to carry it up to the apartment to charge it.
      - I've been forced to re-register my wheel 3 times now as it seems to forget the initial installation and resets itself. = Could be stolen if someone just connected to it when this happened.
      - Flykly support is very slow and their responses is often not very helpful and very vague. Avoiding and making excuses. Getting nowhere.

      The good:
      - Once you are on you way, it works pretty well when accelerating and going up hills. It is fun, but it has way to many flaws that ruins the experience.

      After 1,5 years +(?) of constant delays they finally delivered a product that feels very unfinished with lots of flaws. Disappointing.

    18. Creator theadrew on May 12

      @North I'm also concerned about the battery management system as I am not getting the "green" light to come on as described in the instruction manual. I haven't seen the icon for BMS problems though. I know improper BMS can ruin the battery cells though through overcharging or poor regulation and distribution of current.

      @M.Eichar You should buy a chainring with fewer teeth. Count your teeth and find one with at least 4 less. EG if you have 52 teeth now then go for 48 or 46. This will make it easier to accelerate and more importantly easier to pedal uphill which will keep motor engaged.

    19. Creator North on May 10

      Hi. I set up the wheel and put the charger on overnight. The next morning the red light was still on and when I connected to the wheel I had to go through the registration process again. On the app screen, the icon for battery management system problems is on. Anyone else experience this? How can I fix it?

    20. Creator M. Eichar on May 7

      After a bit of fiddling, I've got my SmartWheel functioning well, but I'd like a little more help getting up the hills - main reason for getting the SmartWheel in this hilly town. The hills aren't particularly steep; I was able to pedal up them a few years ago before my knees got too bad to do it.

      I've tried to let the wheel do the work up the hill, as Niko showed me, but it slows down too much, and I have to get off and walk it up the hill. The resistance is such that I can't force the wheel to keep turning. Anybody have any advice on the best settings?

    21. Creator theadrew on May 7

      Noticed today that my charger gets extremely hot after two hours of charging- hot enough to not want to leave it charging with I'm not home. Anyone else? Also to charge from 5% to 100% took about 3 hours 15 minutes. Anyone get a green light on charger after full charge?

      @Brian Dionisi - sometimes while riding I pedal backwards and then pedal forwards if wheel doesn't want to turn on after a stop sign. As for resistance with the wheel off there is a little from the added weight but its not like pedaling through regenerative brake resistance or anything. Take your chain off and see if the wheel spins freely when the bike is on a bike stand or upside down on floor. Try to figure out where the resistance is coming from. Maybe try a different bike frame too. With the chain on the wheel wont spin long unless you continually pedal. With the chain off it will continually spin (until you apply brake) after a helping manual hand spin.

    22. Creator Julian Helmich on May 7

      I am always successful with the bluetooth connection when I completly close the flykly app, reconnect bluetooth in the settings, start the app again and connect. Holding the phone close to the hub helps.

    23. Creator Brian Dionisi on May 6

      Received my wheel about a week ago.

      While I had some initial success connecting with Bluetooth (enough to setup my wheel settings), I've since been unable to connect at all, even with the wheel plugged into a power source.

      More recently, while the wheel still lights up, no amount of pedaling will get the assist to kick in. So currently the wheel is nothing but dead weight and completely useless. Thanks FlyKly.

      Assuming it starts working again, is the wheel supposed to have resistance? Despite not rubbing against brakes or frame, the wheel won't spin freely for more than a rotation or two. Someone pointed out that the hub/axle were incredibly tight. Has anyone dealt with this? I'm hesitant to tinker with the hub.

    24. Creator Andreas Steen on May 4

      @james
      Sometimes the bluetooth connection works if the charger is connected. Please try that out.

    25. Creator Paulo Devera on May 3

      @james. You have to turn off your bluetooth, turn it on again, connect to your flykly, go to app, connect. I know, it sucks!

    26. Creator Jesse on May 3

      @james it sounds like they forgot to config your bluetooth module... I don't think it can be done over bluetooth, has anyone figured out the pinout for the flykly connecter yet? If it's like the Zehus, there should be some sort of serial data cable that allows you to connect the wheel to a computer to finalize it's settings... you might have to ship the wheel back if they wont supply you with the tools necessary to do it yourself.

    27. Creator James Dichter on May 2

      Ok. Here is the problem-- appreciate help.

      My iPhone Bluetooth does find the Smart Wheel which shows up as device RN-AIP-48A5.
      And is able to connect.
      But my iPhone Smart Wheel app doesn't see the wheel is connected. When I hit 'connect' on app I receive error message to go to Bluetooth and connect with Smart Wheel.

      What now? Without being able to open app my Smart Wheel is useless.
      Thanks,
      Jim

    28. Creator James Dichter on May 2

      Andrews,
      Unfortunately my iPhone has not been finding the Smart Wheel putting the iPhone next to hub. It does find device RN-AIP which I am able to connect with. Buy that does not help when I go to Flykly app and press connect.

      What device name does your Smart Wheel show via Bluetooth.

      Appreciate any help-- very frustrating.
      Jim

    29. Creator Andreas Steen on May 2

      @James
      You have to put your iPhone directly near the HUB, otherwise your Flykly will disconnect. This Bluetooth issue has been described here several times. Then you have to do your individual settings and after that procedure you do not need your iPhone again for Flykly with the exception of settings changes.

    30. Creator James Dichter on May 2

      Can anyone help me. When I turn the Smart Wheel on the blue light indicated is very faintly blinking. (Should the blue light be solid or brighter?

      Then When I turn on Bluetooth on iPhone no device shows up named Flykly or Smart Wheel.
      I do get a device called RN-IAP-48A5 which I can connect to.
      But when I go to Flykly app to setup and press Connect I get error message about going to Bluetooth and connecting to Smart Wheel.
      Have tried on several iPhones with no luck.

      Any thoughts on how to get Bluetooth connection to Smart Wheel so can use App. At this point wheel is of no use.
      Thanks.
      Jim

      I have emailed Flykly folks with no reply on this Bluetooth connection problem.

    31. Creator Andrew R on May 1

      M. -

      Did you go through the wheel setup in the app? It's sort of hidden but the instruction book has a bit about it. Mine didn't assist until I did this and I was a bit confused at first. I'll likely never learn to read instructions before just trying a new tool out for myself but it would save me a lot of time to do so.

    32. Creator M. Eichar on April 29

      Can anyone help me? The wheel arrived two days ago, and I plugged it in and charged it to be certain the battery was full. Since it's not compatible with my hybrid, I had to get a new chain. I took it to a reputable bike shop in town, where they installed the chain. The owner and the bike tech were excited about the wheel, and are interested in bringing it into the store, so I let the tech try it out. Epic fail! I got it connected to my iPhone6, and sent him off, but despite a small amount of assist at the beginning, it disconnected while he rode. We tried again, but same thing.

      Discouraged, but optimistic, I took the bike home and tried it out. There's no assist whatsoever and I had to push it up a very minor grade, one that I would normal cycle up in a high gear.

      What am I doing wrong? Does anyone have any tips for me? I'm pretty sure there's a secret that I don't know, and if any of you who are happy with your bikes can share, I'll be grateful. I'm going to email Niko, too, as he should know there are shops that want to stock the wheel...if it works.

    33. Creator theadrew on April 29

      update: bluetooth issues aren't as bad as I had thought (MAY work from handlebar to wheel distance for real-time adjustments). But having to re-connect phone to wheel from dropped bluetooth connection with wheel is common and required before entering app to make adjustments.

      @paul devera my first ride I got 19 miles on modest settings for half then top speed settings for second half over relatively flat terrain in Chicago. I weigh about 170 lbs and have a mid 80s schwinn traveler steel frame. I suppose that the 30 mile range is only to be expected for factory settings which are around 60-65% I think. My battery wore down to 11-13% and I noticed that the force on my top settings felt reduced by 50% or more. To me, this means that the top 3/4 of the battery charge will perform better than the bottom 1/4.

    34. Creator James Dichter on April 29

      Has anyone been able to contact Flykly and receive support for Smart Wheel not working with your bike? Sent emails with photos showing problem and asking for help/solutions. No reply.

    35. Creator James Dichter on April 28

      Liked the idea of changing to 18t 3/32 sprocket but after talking with the senor bike mechanic at the leading Boston bike store he strongly advised against going this route.

      This guy works on a number of electric bikes and said way the SW sprockets was attached was a really bad system. Also thought trying to put on another sprocket could be a can of worms. Wouldn't touch it in his shop.

      He said that if I did replace the sprocket the torque of SW would not be very good for my bike's front sprocket and the derailer.

      If you have good success changing the SW sprocket and having your bike work well please post.

      For now It seems I have a non-usable expensive Smart Wheel unless I buy another bike.

    36. Creator James Dichter on April 28

      Ok, so we all find the Smart Wheel will not work on our multi gear bikes as we were assured it would. That Flykly is not helping to resolve the problem and still giving false information on their website is disturbing.

      Replacing the Smart Wheel sprocket to fit my chain/bike may work. ButI was told by a few bike guys that the more heavy duty single speed chain was needed to deal with the torque on the Smart Wheel. Any thoughts on this? And if SW sprocket is changed will there be an potential damage to my Derailure?
      Thanks for any info.

    37. Creator Andre Wendt on April 28

      Regarding Derailer and problems you guys have - easiest us to keep the chain and Derailer setup and change the sprocket on the flykly.
      You need a 18t 3/32" sprocket, suitable for fixed gear setup, no freilauf setup!

      Flykly recommended me a shop in Slovenia to order that.

      Good luck and enjoy.

    38. Creator M. Eichar on April 28

      Too bad we can't edit or delete these posts...Update: The wheel in no way fits the hybrid I wanted to use it on. The hub axle bolts are too big for the rear derailleur hangers. I'll check out my mountain bike, and if that doesn't fit, it's down to the local bike shop to find something that does. This is in no way a criticism of FlyKly - there are too many bicycle variable for them to attend to all of them - but it does mean extra time and possible money before I can ride.

    39. Creator M. Eichar on April 28

      My wheel has arrived, and I'll have to do some derailleur-type magic for it to fit my bike (see below) but I'm excited to have it in my hands. It was a long wait, some communications lags, but all in all I'm really happy that I backed this project.

    40. Creator theadrew on April 27

      Up and running here. You'll probably need an 1/8" chain (wider than my previous 3/32" chain). This is because the sprocket it comes with is thicker (1/8" size). So yes it will wear out your front sprocket if you continue to use it with a 3/32" front sprocket, but it does still work with a 3/32" front sprocket. I removed my derailleur too, but did not try and see if it would have worked. I have found that bluetooth connection is bad. It's bad enough to not expect any real time adjustments or distance/ speed/ battery measurements. You'll have to stop, get off bike, go to settings, go to bluetooth, make sure wheel is on by spinning wheel with the pedals, hold phone near hub, hit connect to flykly from list of bluetooth devices, wait for connection, open flykly wheel app, enter passcode, go to settings, adjust assist or brake or top speed, and hit save. It would have been nice to auto connect to wheel through bluetooth when in range, but I have to manually go in and re-connect every time it gets 12-15 inches away from hub (disconnects). You'll have to do this to change assist or brake or speed levels from previous settings. My distance and battery info seem to update when I re-connect.

    41. Creator Andrew R on April 27

      I planned to install the wheel on an older road bike and it didn't seem to work with the multi-speed chain as others have mentioned. Bought a fixed gear sprocket (bike long overdue for an upgrade anyway) and single speed chain and it works great. Does not seem to be compatible with any bike as advertised, at least not with the sprocket it ships with.

    42. Creator James Dichter on April 27

      After finding my Cannondale hybrid chain did not fit with the Smart Wheel sprocket --- I went to REI today. The top bike repair guy said the Smartwheel needs a single speed chain which is wider and heavier then my bike chain. But apparently this single speed chain can not be used with my derailleur . And even bypassing the derailleur doesn't help for the REI guy indicated the wider chain will ruin my pedal sprockets. the FlyKly says many times their product can be used with multi-gear derailleur bikes. is the REI guy wrong?

      What are my options?
      The Smart Wheel seems to require buying a new single speed bike. the single speed bikes I have seen are fixed gear which will not work with the wheel!

      if there is an easier solution please post it.

    43. Creator James Dichter on April 27

      Does anyone have Flykly phone number? The number listed from Switchboard and other sources is now a Hawaiian water company!
      sent several emails with no reply.

    44. Creator James Dichter on April 26

      I am also having a sprocket problem with installing the Smart Wheel. My chain links are a different distance then the wheel's sprocket teeth. The chain does not mesh and therefore quickly comes off. bike is a Canondale with 24 speeds. The company said the wheel is compatible with a derailleur. It seems any chain that fits the Smart Wheel sprocket will have link lengths that will not then fit my pedal sprocket. Am I missing something?
      Any suggestions?

      Got my wheel on Wednesday. Took about 14 days via air Slovenia post. Then usps took over. Charging wheel now. I have a deraileur I might leave in place but we'll see how the chain fits. Anyone try the android smart wheel app or is the iOS favored for now? Ill report back on range but ill probably break it around 50-60% settings max. The charger has a proprietary 5? Pin connector on the end that connects to the wheel so we won't be ordering spare chargers off eBay ;( .

    48. Creator Eben Polk on April 23

      I recently received my wheel in Oregon. Shipped from Slovenia via air. Very excited to try it out.

      When starting to install the wheel I noticed that, per the manual, each axle has flat sides that align with the dropouts, letting you slide the wheel securely into place in a fixed position. However, on my axle the flat sides on the two ends are not aligned, or not parallel. The flat sides point off in different directions. So, when I rotate the wheel so that one end of the axle can fit into its dropout, then the other end of the axle on the other side of the wheel no longer fits.

      Has anyone had the same issue? If so, has anyone been able to torque the two ends of the axles so the flat sides are aligned and can fit into the dropouts? I submitted the same question to FlyKly and if I hear back from the support people I will share the response on this forum too.

      Been running my flykly for a few days now. While the ride is pleasant, it is in no way powerful. Nowhere near the promised range. Im getting about 13 miles for full assist full speed with 16% only battery left. Is anyone having range issues or can we share data on your rides? This may be an isolated issue which is why i would like to share information. Here is my ridewithgps data.

      Please share your range so we can find out if we got a dud or not. Thanks.
