Folding Electric Bike 40km Range

A folding e-bike that turns a 40-minute commute into a 15-minute ride. The motor pushes you to a top speed of 30km/h, and a 40km battery range means most riders charge once or twice a week instead of every night. Fold the frame and stem and it fits in a car boot, a flat entrance hall or a small apartment lift.Three riding modes let you choose how much help you want: pure pedal for exercise, pedal-assist for effortless hills, and full electric throttle when you'd rather just cruise. Fat all-terrain tyres, front suspension and disc brakes make it just as comfortable on gravel paths and beach fronts as it is on tar. Top speed of 30km/h Up to 40km of range per charge Three riding modes: pedal, pedal-assist and full electric Folding frame and stem for car boots and small spaces Removable battery — charge it at your desk, not in the driveway Front and rear disc brakes with motor cut-off Fat all-terrain tyres with front suspension LCD display with speed, battery, mode and trip distance Integrated LED headlight, rear light and rear cargo rack Rider weight capacity up to 120kg

A city-ready folding electric scooter built around a punchy 350W motor that handles Johannesburg hills, campus commutes and the last mile between the taxi rank and the office without breaking a sweat.

A backlit handlebar display shows speed, battery level and ride mode at a glance, and the front LED headlight plus rear brake light keep you visible in early-morning and after-work traffic. 350W brushless motor with strong hill-start torque Three ride modes: Eco, Standard and Sport Fast one-latch folding stem for boot, bus and lift storage Dual braking system with regenerative front braking Backlit LCD display: speed, battery, mode and odometer LED headlight and rear brake light for night riding Shock-absorbing front tyre and rear suspension Cruise control for longer flat stretches USB-C charging port for your phone on the go Rider weight capacity up to 120kg

My car stays parked now

I ride 14km to the office and back and still have battery left. Folds into the boot when it rains and the three modes make the hills a non-issue.

Perfect for the last mile

Taxi to the station, scooter the rest of the way. It handles the Sea Point promenade easily and folds small enough to carry into a meeting.

Filming without stopping

The 8MP camera is genuinely handy for hands-free clips and the open-ear audio doesn't block traffic noise. Battery gets me through a morning of use.

Tiny, tough, does the job

Clipped it to my helmet for a weekend trail ride. Footage was steady, mounts held, and it weighs almost nothing in the bag.

Solid build for the price

Brakes are confidence-inspiring and the lights are bright enough for early mornings. Wish the fold latch was a touch easier, but I'd buy it again.
