How it works

From your bicycle to an e-bike in three steps

No new frame to learn, no licence, no fuel. You keep pedalling; the motor does the heavy part.

  1. 1

    Check it fits

    Send a side-on photo of your bike on WhatsApp. We confirm the wheel size and frame, then quote.

  2. 2

    We fit the kit

    Our mechanics fit the motor wheel, battery, controller and display, and set the assist for the loads you carry.

  3. 3

    Charge it, ride it

    Lift the battery out and charge it from any wall socket in six to seven hours. Pedal, and the motor helps up to 32 km/h.

On the road

Built for real work

Water, crates, deliveries and people, on the same roads our riders use every day.

Running costs

Petrol eats profit. Electricity doesn’t.

The same 100 km of work, side by side. Figures reported by The National from our Kampala workshop.

Petrol motorcycle, fuel for 100 km15,000UGX, and it rises with every pump price. Plus oil and a monthly engine service.
Karaa e-bike, charge for 100 km700UGX from a wall socket. No engine, no oil, no fuel queue.
