ONESPORT OT02 PRO · Lightweight Retro Foldable E-Bike
17.18kg of lightness, 30N·m of refinement
Most electric folding bikes weigh around 25kg – a struggle in lifts, a burden when carrying upstairs, a back-straining effort to fit into a car boot. The OT02 PRO weighs just 17.18kg – nearly 8kg lighter than comparable models. This weight means you can carry it folded with one hand up three flights of stairs, place it effortlessly into a car boot, or carry it through a ticket gate during rush hour without slowing anyone down.
The lightweight construction comes from the chromoly steel frame – stronger than ordinary high-carbon steel, allowing for thinner wall thickness and a significantly lighter overall package. The 20-inch folding frame, paired with a torque sensor, delivers smooth, seamless pedal assistance – no jerking, no hesitation, no freewheeling. A 25km range is precisely right for short commutes – it is not for crossing cities, but for covering that last mile from the station to your doorstep without walking.
Retro details – not decoration, but attitude
A brown leather-look saddle with antique brass rivets, available in green and red finishes – this is not a modern e-bike wrapped in bulky battery housings and oversized tubing. It is a retro-styled bicycle, simply with a motor and a battery added. Mudguards keep splashes at bay; the leather-look saddle outlasts ordinary foam padding; the craftsmanship holds up to close inspection. Folded, it measures a compact 84×38×64cm – unobtrusive in an office corner, space-saving in a hallway.
Torque sensor – assistance that feels like "I'm pedalling lighter"
The OT02 PRO uses a torque sensor – not a speed sensor. The difference: a speed sensor pushes as soon as it detects movement, regardless of whether you are pedalling lightly or heavily; a torque sensor measures "how hard you are pushing" and delivers proportional assistance. Starts are smooth, acceleration is linear, and there is no sudden lurch. The 1×7-speed drivetrain, paired with 30N·m of torque, is more than capable for everyday urban conditions.
Who it is for
For those living in older buildings without lifts, who fold and carry it upstairs every day. For commuters covering that last kilometre or two who do not want to walk or wait for a bus, who need a bike that can easily be taken on the train. For weekend trips to cafés or parks, without the hassle of driving or crowded public transport. Riders from 150-190cm can find a comfortable riding position, with a maximum payload of 80kg – covering most daily commuting scenarios.
The essence of the folding e-bike business is not about cramming a battery and motor into a frame. It is about ensuring that even without power, the bike remains a good bike. The OT02 PRO delivers on that.
