This shows Michael's new Greenspeed GTR trike. It's a little different to many (as if recumbents aren't unique enough as they are) as it doesn't have any external gearing but still manages to be 28 speed (gear inch 13" - 117") - it originally was intended to be tooth rubber belt drive as well but that didn't eventuate.

2 speed internal Schlumpf front BB. | The button in the centre toggles in and out to change gears. | The black hoop is a bike lock. Turn a key and a pin is slid between the spokes to imobilise the machine. | ||
Rolhoff 14 speed internal rear hub (OEM version) | Note quick release. | 2 cables come from the hub. | ||
The OEM version of the Schlumpf doesn't have a torque arm but engages in the dropout. | Bottom half of the handle is the gear shifter. There's only 1 gear lever aneeded - it turns directly from gear 1 to 14 in one sweep. | |||
