      Despite update #21, I have NOT received the wheel nor any shipping information. And I was an early backer! Ugh!!!

    2. Creator Jesse 1 day ago

      The bluetooth problem is because the wheel is metal, and the antenna is inside the wheel. It really needs some sort of external antenna, those plastic covered holes are the only place the signal can get out of the inside of the wheel. The original wheel was supposed to be plastic, so it would not have caused any interference problems.

      @grove: no, no solution yet, it's very very very sad, that they haven't used 4.0 like promised.

    4. Creator Grove Media Studios 2 days ago

      The Bluetooth range is horrific on the wheel. It cuts out within 12-ins of the hub. Is there any fix for this?

    5. Creator Bernd 4 days ago

      In time for my birthday I got my flykly back. After an additional procedure of de- and reinstalling the app and setting up the wheel newly it is finally operational again, hopefully this time for more than 300 km. Keeping fingers crossed! Thanks flykly.

    6. Creator Waldir Pimenta 4 days ago

      @Andrerson Carlos Faller, you might want to reconsider. I just got the email notifying me of the shipping of my wheel, and I was probably among the last backers, since I waited until the last day because I was waiting for Copenhagen Wheel to announce their price as they had promised (they didn't). Assuming Kickstarter rewards are being sent in order, yours will probably arrive soon too, then.

    7. Creator Anderson Carlos Faller 5 days ago

      I'm asking for my money back, it's been 2 years since I financed this project.
      In the FlyKly website, they estimate a delivery time of 3 months. What's wrong with the backers' rewards then?
      Since they have a 30 day return policy anyway, I don't see why having my money back would be a problem.
      I don't even own a bike anymore...

    8. Creator Tedly Melis on October 2

      Wow - I'd nearly forgotten that I had ever even been an early FlyKly backer - has it really been 2 years now since I was foolish enough to believe in Niko's entraprenurial magic:

      Ponzi Scheme:
      "A Ponzi scheme is a fraudulent investment operation where the operator, an individual or organization, pays returns to its investors (or not) from new capital paid to the operators by new investors (buy one today), rather than from profit earned by the operator."

      Above statements made with due respect and consideration (more than we have been collectively afforded as investors apparently)...

      It's OCT now, and I'm buying a brand new rear wheel for the Planet Bike build up I have had sitting in the garage now for nearly 2 years - there's no power like pedal power...

      Hasta Mañana - Tedly

      Regarding use: the wheel is interesting. The wheel does not employ a true torque sensor but instead is activated when the cog is at close to the same rotation rate as the wheel. If pedalling cadence is slowed down, the cog begins to freewheel and the motor cuts off. Assist level seems to be tied to how much the cog is allowed to freewheel before the motor cuts off.

      This has some interesting consequences. For instance at 30% assist, the wheel allows me to accelerate quickly as my cadence keeps the chain tight and the cog at the same rotation rate as the wheel. But as I get up to speed, my cadence is not keeping up with the wheel and the motor cuts off. The wheel's internal resistance slows me down a little, my cadence catches up, and the motor activates again. It is an odd slow-and-go sensation and involves a lot of quick pedalling in attempt to keep the motor from cutting off. This can be alleviated by increasing the assist to 50% or so, but then fine control at slow speeds becomes a little more herky-jerky.

      And, sometimes the wheel seems to get confused. At one point it activated the electric brake when I was not back pedalling and only began assistance once my speed had slowed down considerably despite applying torque with the pedals.

      I think I liked the feel of 30% assist, but I was pedalling like a hamster on a long smooth straight away only keeping up with other cyclists. A larger chainring should help out here. Or, I will up its assist level as I get used to the wheel. Nonetheless on nice smooth routes, the 25km/h limit becomes noticeable as pedalling cadence is too high to push my bike faster after the motor cuts off.

      I received a new freewheel assembly, and the wheel works now. Before I installed it, I spread some epoxy over the magnet assembly to shore up them little magnets. Anyone doing this be very conservative with the epoxy as the clearance is tight and the magnet assembly must spin freely with the freewheel. Also care must be taken to not gum up the adjacent bearing.

      Re shipping, I think the problem might be with Slovenia post. My wheel took over one month to arrive to Canada while the new freewheel was here in 7 days. It seems their service is inconsistant.


    11. Creator J. Corbett Hix on September 29

      My wheel supposedly shipped over a month ago to Cambodia and is nowhere to be found. I’ve asked for confirmation that it was sent by air and a scan of the shipping bill, these questions have been ignored by your support. I’ve requested status info and it seems your carrier can still not identify the wheels location. Numerous calls to the post office here with tracking number show no product. All this and I originally had requested the glow in the dark but settled for the white to get it earlier. I was told that I would have it in August, it is not almost October. I had hoped to bring this with me on a holiday (I leave Saturday), this will not happen.

      Tracking status shows Shipped 24 AUG

      Dave & Clarence - What was the ship date for your order?

      Jesse - Have you found a more public place to post complaints? I think it would be helpful to warn potential future customers. Unfortunately, their facebook page does not have ratings or allow comments (probably for reasons below).

    12. Creator Jesse on September 26

      People,if you want flykly to actually respond to your message, don't leave it here. Instead, go to
      and click "contact me". It's the only way I've found to actually get a response.

    13. Creator Dave Greenberg on September 24


      I'm wondering where I can go to find an update on shipping information or a delivery schedule for the wheel I ordered. I'm in the bay area - California. I already see people selling their wheels on craigslist so I just want to make sure mine isn't missing in transit or something. I've never received any information on what to expect. Backer number 2231 so I guess I might be on the back end of fulfillment. That's fine, I get it - I just want to have an idea of when I can expect it.

    14. Creator Clarence Ziting Zeng on September 22

      Dear Flykly,

      I'm in Singapore, and I have not received the wheel. It's almost the end of September 2015.

      I paid so much. WHERE IS MY WHEEL?

    15. Creator Reynard on September 22

      Dear Flykly,
      I'm in the US midwest and still have not received the wheel. I was told that the 2nd batch should ship at the end of August at the latest.

      I know you are trying to sell more wheels to make some profit, or to recover some loss from this mess. I see you started posting google ads to sell the wheels. But the best marketing you have is your early backers, so why don't you make sure all the backers get their wheels instead of wasting money on google ads. When I get my wheel, for sure lots of my friends would be trying it. I'm sure that would be true for all the backers, they would be showing it off to all their biker friends. That will be a much more effective marketing than google ads!

    16. Creator Lou Peguero on September 21

      Backer 1,887!!!!! Pledged $590 of my hard earn money on November 14, 2013!!!!! STILL NO WHEEL!!!!!! NO SHIPPING NOTICE!!!!!!!!!!!! NOTHING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    17. Creator Vitoon Utaranakorn on September 21

      Dear FLYKLY Team

      I would like to know why I have not received the reward. I love to order FlLYKLY but I am terribly disappointed that I have not received the reward as pledged. I am from Thailand and my pledge was this:

      $590 reward on Tuesday 19 November 2013

      Backer #2,092

      $590 USD - FLYKLY SMART WHEEL - Get your very own Smart Wheel with Smart Light included! Worldwide shipping included.

      Ships anywhere in the world

      Shipping Update FKYKLY Said

      ".. We’re starting with second batch in June and estimate to get the Smart Wheel to all Kickstarter backers until the end of August."

    18. Creator Francis Sothy on September 20

      May I have a delivery date? Great to hear lots of folks are getting serviced but some of us have not received our initial reward from the initial Kickstarter funding.

    19. Creator Bernd on September 19

      Hey guys. I'm also still waiting for repair or replacement. It's nearly 8 weeks now. I don't know a timeframe how much longer to wait, so I can't decide whether to buy a conventional replacement wheel for my bike. I think season will answer this question for now, because it's a racer.

      @jesse: I'm not sure about the lock feature in my blue light case, haven't used it too much.

      @keith: good news at least for you! :)

      @andrew: to pay for warranty shipping wtf?

    20. Creator Jesse on September 15

      We really need a forum for the flykly wheel. kickstarter comments aren't really the best format for information sharing. If no one else wants to start one, I'd be willing to set one up on one of the free fora sites. Are there any of the "hacker" edition backers out there? I'd love to hear from them.

      @mitch, you won't be able to do a chargeback this late.

    21. Creator Mitch Evans on September 15

      Alright I've had ENOUGH! YEARS of excuses and more excuses. Flykly told me a month ago they would try and ship all devices in Aug. As of today haven't heard a damn thing. And now they are already shipping replacements to people when I haven't received my initial one? I'm filing a credit card dispute tomorrow and getting my money back!

    22. Creator Keith Jackson on September 15

      Woohoo. FlyKly got back to me and will send me a new freewheel assembly. Thanks!

      I will post back in a few weeks on whether it works.

    23. Creator Andrew R on September 14

      @Jesse - I finally got a response on Facebook saying they want me to pay to ship the wheel that died after only a few miles of use back to Slovenia so they can "repair" it. If our friend below who has waited over 6 weeks for his repaired wheel to be returned is any indication, this does not bode well. Even if they do repair and return it, I'll have little confidence that it won't die on me in the middle of a long ride and they certainly won't do anything to fix the terrible Bluetooth connection range.

    24. Creator Jesse on September 11

      @ Andrew have you tried contacting them through the kickstarter page? It's the only way i've found to actually get them to reply.

    25. Creator Andrew R on September 11

      @Keith - sorry to hear about yet another defective wheel. Plan on waiting a lot longer for a response. I've been sending email for two weeks about a completely dead wheel and have heard nothing other than one empty promise via a Facebook post.

    26. Creator Keith Jackson on September 10

      Mine worked for two laps around the block, then assist and brake are not working. Everything else works, bluetooth, wheel lock, speed indicator. I suspected it would be to do with the Hall sensor.

      I removed the cog (as per video instructions, and not voiding warrantee) and found a bunch of tiny magnets stuck in random places. Inside the cog assembly is a plastic ring that holds the magnets, from which the floaters fell out. It seems that the glue holding the magnets in was not up to the task. I could not locate all magnets to reassemble the ring, but I put as many back as I could find and epoxied them into place. Unfortunately, assist and brake still do not function.

      I have asked Niko to send me a new magnet assembly (a small inexpensive part) rather than sending the wheel back to Slovenia, then to Italy, to the lava pits of Mount Doom, and back to Canada. No reply yet, after almost 48 hours.

      Note if you suspect you have the same problem, the Hall sensor magnets are retained in a small white plastic ring inside the cog assembly. In Niko's video on cog replacement, he refers to the four freewheel pawls as magnets that might fall out. Hmmph. Those are not the Hall magnets, they are not magnetized and are part of the mechanical freewheel.

    27. Creator Jesse on September 7

      Well, I've got good news and bad news.
      The good news is that if you get the solid blue light error, simply disconnecting it from the charger and letting it sit for 1-2 days will discharge the battery and then you might be able to get the wheel woking again.

      The bad news is that the battery drains by itself in 2 days. Also, I'm pretty sure the wheel lock feature is what is causing this "blue light error", at least in my case. When I lock the wheel, it sometimes locks and sometimes it doesn't, and when it doesn't, the bluetooth shuts off and it won't turn back on until the wheel is discharged.
      Some more bad news: the "help desk" on the website never responds to emails sent.

    28. Creator Jesse on September 6

      I just got my wheel hooked up, went through the registration, finally got it connected, mounted on the bike, and the next day, when I went to use it... it's solid blue, no assist, no bluetooth :(

      I didn't even get to use it once!
      There needs to be some sort of hardware reset button for this thing.

    29. Creator Andrew R on September 5

      Thanks Bernd. Are you in Europe? Hoping I can send mine to NY for repair as it's not too far from DC. Actually hoping they'll do an exchange for a new one instead. Per your request, adding to the early failure list:

      Please add yourself to the list, if you have encountered the same issues, as I believe I'm not the only one:
      1. Bernd (on cold flykly turkey now)
      2. Andrew R (charged, no longer powers on)

    30. Creator Jan E. Bolte on September 4

      Hello FlyKly

      Any news on delivery?

      You said, we ship orders on a first come, first served basis. Estimated delivery time is 3 months.

      Who came first, who is served first? I did order on the 22nd of October 2013; estimated delivery May 2014, financed 25th of November 2013.

      So, we're going fast on 2 years now. I don't really understand what the difficulty is: assemble the bike, pack it, and send it off! You have the address.

      Cheers, Jan

    31. Creator Jesse on September 3

      what kind of valve is on this? it looks sort of like a cross between a presta and a schrader... It has an internal pin like a schrader, but the diameter of a presta, and so my pump wont fit on it.



    32. Creator Bernd on September 3

      @Andrew R: Yes, kind of, but mine was showing a permanent blue light, and not smart any more, giving no motor support, not being on air via bluetooth. Sent it back to Slovenia for repair more than 6 weeks ago but since then I was only waiting. The issue happened after 300 km total usage without one single raindrop and after a 1h pause. Directly before this pause the wheel was in normal usage in the city without any extra strain e.g. hills or high temperatures. Please write yourself to the 'early damage list' I created down here if you like. I fear we are not the only ones. :-(

    33. Creator JVVH on September 3

      Received my wheel yesterday. Haven't opened the box yet. The box is damaged on one side and torn open around the axle. The axle nut is a bit scraped up. The box looks like it was reused, there are multiple staple holes.

    34. Creator Steven Santa Maria on September 2

      Another month gone and I still haven't received my tracking number. I was a member of the original funders for this back in 2013. Needless to say, I'm disappointed in the lack of communication... Flykly can you help?

    35. Creator Amanthus Lunn on September 1

      *Sigh* I am located in the US. I still haven't received the tracking number for my wheel, so I am guessing it still hasn't been shipped yet. Multiple emails sent back and forth through this whole process, always with a response giving me false hope of receiving my wheel. Last email said August and now it is September. I have been INCREDIBLY patient through this whole process. I understand delays, they are typically when creating new products, I TOTALLY get that. But seriously, this is getting ridiculous. Flykly communication and transparency of behind the scenes is ugh. Alright, rant over.

    36. Creator Andrew R on September 1

      I was lucky to get my wheel a few months ago and was pleased with it. Now after very light use due to other time commitments it will not turn on even though the app just a few minutes before it died showed full charge. No response yet to emails to Flykly. Anyone else with a prematurely dead wheel?

    37. Creator Andy Lauw on August 31

      Got my wheel + smart light today (Perth, Australia). Everything seems to be working ok, though have not had the chance to install it on my bike - maybe tomorrow's job.
      Late better than never. Thanks Flykly.

    38. Creator Sanyu Ye on August 29

      It is end August now. I am still waiting for my wheel

    39. Creator Vitoon Utaranakorn on August 27

      Still have not received mine. Where is The FlyKly ?

    40. Creator Phillip Dean on August 26

      My wheel arrived yesterday (California) so the latest shipment to the U.S. is arriving. Sadly I've spent most of my free money on a new motorcycle so it is just going to sit there in the garage for a while :(

    41. Creator Bernd on August 25

      @Brian: My wheel is still under repair in slovenia (for more than five weeks now). Flykly is more or less a one man show, look at all these guys, who have never received their wheel yet. Summer is over now. I too build up a new light weight (14,4kg) racer only for the wheel. Hopefully I will see mine again, before snow starts falling...

    42. Creator Henry Hui on August 21

      Hi, I'm still waiting for my wheel to be delivered. Please advise the current status or any thing I may have missed.

    43. Creator Dan Gray on August 18

      I received my wheel and no longer have a use for it. Anyone looking to purchase, please reply here. Located in CA.

    44. Creator Grove Media Studios on August 16

      I also got a tracking email from Slovenia; when I check the tracking through, it just keeps saying bad data, no updates. Anyone else have any issues with it?

    45. Creator Alexandria Stevens on August 12

      I emailed last night and my response was a shipping tracking number, from Slovenia. I was told that there was a huge shipment to the US and that it would be broken down for individuals from there. Waiting now to see how long it takes me to get my wheel.

    46. Creator Stephen Wilder on August 12

      Any updates, FlyKly?

    47. Creator Purin Phanichphant on August 9

      I backed the Flykly project 2 years ago. Their delivery dates kept slipping from 6 months, to 1 year, to almost 2 years now. When they finally were ready to ship, they asked for my preferences and shipping address. One April 9th of this year, they even sent a shipping tracking number (from Slovania!?!) to me.

      I've been patiently waiting for about 4 months now, and still have never received my reward (which I paid $590 for). The shipping tracking number stopped working, and USPS sent me a letter that the package went missing and they are investigating. I tried to contact Flykly's support, and they have "acknowledged" and will "investigate" my case and there were no further communications, nor were they helpful with issuing a refund nor send me a new reward.

      I decided I've had it and I want my money back. $590 is a lot of money to me and I felt like FlyKly robbed it from me (with the help of Kickstarter).

    48. Creator Stephen Wilder on August 4

      Flykly, what's the deal here? I funded 2 Smart Wheels almost 2 years ago, and have received absolutely no indication of when (or even if!) they will ship to me. I'm in Colorado, and based on what I've read, the US shipments of wheels are well underway. How long do I have to wait to collect on my $1200 investment?

    49. Creator Christian Haag on August 2

      I am having the same BT problems as many here. Connection within 30 cm. more distance --> signal/connection lost.
