Grin All-Axle

Minimal

Recumbent Bike

This is a virtually maintenance free, extremely comfy Flevobike Green Machine. The rear drumbrake, the disc- and regen brake in the front, together with a completely sealed drivetrain with a modified Rohloff 14-speed gearbox, reduces maintenance to changing tyres every few years.

Cut-away of the drivetrain, with a 14 speed Rohloff hub modified to a gearbox at the central pivot. As it is completely sealed to the elements, and sporting a heavy duty single-speed chain, the chain wear is zero. — Drivetrain

With the conversion, I wanted to keep the clean lines as far as possible. This meant that the only practical solution was an All-axle hub in the front wheel. No torque sensor or CA, and a Baserunner controller in the 800Wh battery. Some of the wires and cables are routed within the frame. The Edelux II front and rear lights are fed by the battery (there was a SON dynamo hub originally). — The final look

A foldable cover for the battery and controller. I use this bike mainly in good weather, and have no front mudguard. — Splash guard

I use no CA, just a throttle with a Trip Wire (red arrows) to cut motor power and activate regenerative braking. Magura hydraulic brake in front, and a SA 90mm wire activated drum brake in the rear. I have set the Virtual Electronic Freewheel very high, so this works as a pedelec assist. A quick flick of the throttle activates it, and a short squeeze on the front brake turns it off and gives me an electronic brake with a slow ramp up to full effect. If I want to change any settings, I use a cable and my cell phone. — Minimalistic cockpit

A bespoke seat bag from Radical Design, with quick release and a brake light. This has a retardation sensor, that activates a flashing light in three levels, depending on how hard I brake. Very visible for riders behind me in hectic city traffic. For camping trips I add a set of Banana Bags from Radical. They hold a two-man tent, whisky, camping chair and table, 9cm mattress and everything else you may need for a good life on the road. — Seat bag with brake light
