You replace your rear wheel with a brand new one, with a motor in the middle.
Your new wheel matches your bike; choose the size, rim colour, spoke colour and number of speeds.
Rear wheel motors are safer than having the extra weight of a motor on the front wheel.
Your battery weighs only 1.5kg and fits in place of a water bottle.
It has a key to securely lock onto the bike, and unlock to charge.
Our controller is the jewel in the crown; it's a UK developed, automotive
grade circuit board hidden in the battery mount.
The controller has a single cable to the motor and talks to our phone app.
