There have been a few questions about this ~300w ebike and the places it can go. I try to address some of those through experimentation in this video.
Among the tests done, I go over a few speed bumps, jump the curb, zip through some uneven grass, displace some sand, and hit the waves. All on two wheels.
The industrial outdoor grit/grip tape on the skateboard drive wheel helps keep traction in wet conditions, like rain. Without it, the two wheels might break traction and wear out the tire.
This bike has a locking lever on its front fork tube. Normally, it gives the rider a more efficient ride when riding on pavement or asphalt by preventing energy from being absorbed in the suspension with every crank of the peddles.
Since the motor clamps to the inner suspension tube with a couple U-bolts, the suspension must remain locked, as is the case with this bike. Otherwise a large series of jolts on the front wheel may disengage it from the motor’s drive wheel.
Towards the end of the video (6:21 – end) there is also a brief overview of the electronics.
I also discovered that the controller will take 34 volts from an 8s LiPo pack. This makes the whole thing loads more fun with the added acceleration and extra 3 to 5mph boost.
It also seems like the controller actively regulates max current to the motor, preventing damage to it or the motor.
