A folding fat-tyre e-bike: 20 × 4.0 tyres, battery in the beam, folds in the middle and fits in a car boot. City, gravel, sand, snow.
The power unit
Seven gears on a chain, disc brakes front and rear. Placeholder figures, within the realistic band for this class.
Six parts
Wheel, fork, beam, battery, rear triangle, motor: each part comes off on its own. The hinge in the middle of the beam folds it all into a car boot in half a minute.
The brand on the frame
The pivot every part of a bicycle turns on, and the twenty minutes that stay the same in a day when nothing else does. We build one thing, meant to be used twice a day for years.
The brandHouse brand
The house brand. Perno designs and assembles its bikes here: few sizes, mechanics that can be repaired, and a service desk that answers the phone.
