Video Review

Abus Bordo Granit X-Plus 6500
Don't let your Ebike ride off without you, this the best lock I could find, compact (mounts to frame or fits in your bag), super strong, and tough to pick, thieves will move on to an easier option.

New Full Color Display!

This new display is not only great looking, but it works great too, easier to read, day/night modes, easier to program and includes features like power consumption. It is a nice upgrade from the standard displays that come with most kits.

Bafang Hydraulic or Mechanical Brake Sensor, Bbs01 Bbs02 Bbshd

If you don't have cable pull brakes, or you have integrated shifters on your brake mount, or you just hate the motorcycle style Bafang levers.  This part will allow you to use your existing brakes without giving up the motor cutoff feature.

Stop Flats2

Electric bikes encourage you to ride more, and the more you ride the more likely you are to get a flat.  These liners are amazing and keeping thorns from ruining your ride, well worth the small investment.  Make sure you select the size that is best for your bike.
