Kuma Bikes S1 Step Through E-Bike 250w, 25km/h 120km/s Electric Bike


SKU: N/A Categories: , ,

The Kuma bike S1 is our latest stylish low step mid drive bike.

The S1 is powered by the Silent and powerful bafang m420 Mid motor offering 80NM of torque with 5 power levels.

For 2021 we wanted to create the ultimate unisex low step bike. The S1 and S2 are designed to be comfortable to ride without compromising on style. The new smooth weld lightweight frame features sleek integrated front and rear LED lighting.

Both the S1 and S2 come with custom front and rear racks, mudguards and a handy kickstand.

All our new bikes are powered by  500wh Samsung batteries meaning the complete range is now capable of 100km+ on a single charge. All our batteries are now removable and lockable allowing you to charge your battery anywhere. Our new faster chargers allow a complete charge in under 5 hours.

With a Shimano drivetrain and Tektro Hydraulic brakes, and fast-rolling Kenda tyres the S models are the perfect bike to cruise in comfort and style.
