The aluminum double-walled rim and hub motor are already attached in the box. Kits are ready to install right out of the box, all you need to do is replace them with the original tire.
The wheel axle diameter is 10 mm. Steel forks can be filed if the axle does not fit into the dropout because of its slightly larger diameter. Please do not file more than necessary and make sure that it does not damage the forks. Aluminum forks can also be filed with extra caution.
Aluminum rims have openings for a Schrader-type valve. The kit doesnt have a regen brake option.
The controller comes with an SY60 male-type battery connector (Compatible with XT60 connectors).
PAS/Brake Levers are optional. Kits will operate without them. You will be able to use your own brakes.
