Yes! We designed LOCK8 with mountain bikes with disk brakes in mind. Have a look at the design, there is a groove on the back that makes sure that LOCK8 won't interfere with the disk. Over 95% of thousands of bikes we have tested are compatible; most of those that aren't don't have an actual chain stay.
If you have any doubts about the compatibility of your bike then please email us a close-up photo of the back wheel (on the opposite side of the chain) and we'll answer as soon as possible confirming compatibility.
Nope. LOCK8 is fully functional out of the box. It uses Bluetooth 4.0 (also known as Bluetooth Low Energy). You can lock, unlock, change settings and share your bike for free. The alarm will be triggered in case of tampering too. In case your bicycle is stolen we will activate the GPS for you and help you track it down and recover your ride.
If you wish to have an enhanced experience with your LOCK8 then you can add our Remote Services add-ons at a low monthly cost at around US $2 (no hidden costs: you can cancel anytime and there are no contracts). These plans will allow you to offer your bike for rent, track it's location and to receive notifications on your smartphone in case of tampering.
Attempting to steal the bike sets off the alarm, which gives you and the LOCK8 community time to stop the theft. Also the painfully loud alarm would alert everyone near the bike that it is being stolen, giving the thief less time.
To get the lock off your bike you would need a long time and to virtually destroy the bike. The polycarbonate casing will take some damage before being removed.
Your lock will notify on your phone that your battery is getting low on power. The lock holds a small charge so you can release your bike and either charge it while you ride, using induction or via a USB port.
LOCK8 uses Bluetooth encryption to communicate with your smart phone device so you can rest assured that your devices are safe and secure.
If thieves were were professional enough to break this encryption they'd probably be hacking bank accounts instead.
