Herbert wanted a Brompton with the Big Apple tyres – these are 2″ wide but use the smaller 305 wheel size so only work with disc brakes:
It’s now back in Germany, and looking fantastic with matching mudguards and a front motor system:
It’s a common question – which is the better kind of trike? The answer isn’t so easy – both configurations have their advantages and disadvantages:
Gavin’s Racerunner was built from thin-wall Columbus Gara tubing, for a frame weight of around 4kg, and a total built-up weight of under 10kg.
The frame was built on a custom jig to be perfectly straight, and has adjustable fore and aft positioning of the saddle, and adjustable chest plate using a seatpost.
A series of axle inserts allow different wheels to be used, and the camber can also be adjusted.
Cost was £1500 for the frame, inserts, painting and assembly.

Heinzmann controllers are clever – they often use a half voltage tap from half- way along a battery pack to monitor the cells. This causes problems when you try to fit a new lithium battery to an old controller.
To disable the half voltage detection, simplest way is to bridge a diode on the circuit board. These pictures show you which one to bridge, depending on whether your control board is surface mount or not:
