How does the wireless control work?

The kit uses a wireless BTD260 display or the Keyde app, so no cables run to the handlebar. You pair the display or phone with the kit and control assist from there.

Which motor and battery should I pick?

The 250W motor suits flat commuting and legal-limited riding; the higher 500W and 750W options add speed and hill help. The 7Ah pack is the lightest, while the 15Ah gives the longest range.

Keyde says the kit is compatible with about 99% of bicycles and it is CE certified. Check your rear dropout width and wheel size against the kit before ordering, since rear hub kits are size-specific.

Can I add range later?

Yes. The kit is modular, and Keyde offers a Range Extender Battery plus accessories like a phone holder. You can expand the setup after the initial build.

Is it hard to install?

It is a rear wheel, motor, battery and controller job rather than a bolt-on accessory. Riders with basic bike-mechanic experience can do it; others should budget for a shop fitting.

How does it compare with a mid-drive kit?

A rear hub kit like this is quieter and simpler to fit and keeps the bike's gearing untouched. A mid-drive kit climbs better and balances weight more centrally but costs more and wears the drivetrain faster.
