Those steering columns also did not terminate in a steering box just behind the bulkhead; they terminated in a steering box ahead of the front axle. For maximum safety and minimum cost to the NHS the ideal features would be belts and bags for passengers and a traditional long none- collapsible steering column plus spike end for the driver. The model for advanced drivers would have an explosive spike. You've got to be totally rational and devoid of emotion to come up with this stuff.

They're usually only 40 or 50Nm....there's a Bafang one with 160Nm I'd love to try derestricted. Think I could push some pretty big gears with that. |

I can't remember the spec, I thought it was 95 Nm on max. In bottom gear, starting on the flat, there is virtually no pedalling resistance so the pedal goes right to the floor. The other pedal rises of course and, like a fixed wheel, if the resting leg isn't relaxed, up you go. i never saw the point of using the motor to help turn a really big gear, more for helping on hills, so I ride my Bosch motored bike in eco mode mostly. I haven't ridden it for a year. I bought a hub motor bike as a spare and have been using that. It is a gravel bike, more stable on poor surfaces and a bit lighter. I've been using that. The hub motor is much less powerful and far less help on hills but the bike is more rideable without the motor. The other bike is horrible to ride with the motor off. |

Mine is a pig to ride with the motor off too, as I found out when I ran it out of battery a few miles from home. Without the motor it feels like a very heavy bike and the resistance in the drive train is very noticeable. The bigger gears are for going faster. At the moment top gear and as fast as my legs can spin is about 30mph, or about 25mph at a more comfortable cadence. As I don't need 1st gear, and 2nd is still a bit shorter than I need longer gearing would suit my needs better. It would also be better if I fitted a speedbox to defeat the speed limiter (shhh  ). |
