Nice job Andy, pity the battery isn't on the bike though.

This is certainly the best way to use these direct drive motors, on high voltages for speed when they are at their best.

Don't go overtaking any police cars on those private roads though.

I have got used to the battery on my back (balanced weight, light bike) with my DH TWD (downhill, two wheel drive) ebike, it makes the ebikes feel like normal bikes, i tried the battery on the rack it just doesn’t feel right.

[flecc]

On the rack I agree Andy, that's a large heavy battery to have high at one end of the bike. I was thinking of an in-frame casing maybe, though it's true what you say about the bike feel. Our bodies and anything we carry are really sprung weight, remote from the bike.

I couldn't tell the difference, even with a magnifying glass. What's he done to that then eh?. Then I scrolled down and found the "after" piccies.
Extremely impressive looking upgrade.

The kit cost 207pounds, and the Ping battery cost 300 pounds 10 months ago, total cost for this set up 500 pounds.
No import duty
And no tax
Plus around 100 pound for the bike.

Total cost all in up and riding around 600 pounds.

I have updated the pictures in the first post needed to upgrade the brakes plus half a dozen other little changes to improve the overall running of the bike.

Just finished a distance test

Allmost flat no hills to speak of (Norfolk)
Throttle only.
