Bumping up and down kerbs

[stevebills]

The hub motor wheel I showed above is in a rigid bike and it gets high loadings, jumps and very heavy towing, but at four years old it's never even lost a spoke. A properly built wheel is immensely strong, as Danny McCaskill's huge jumps show. Few wheels these days are properly built though, either machine built or built by semi-skilled builders. Uneven tensions are the norm these days, and that always spells possible trouble.

I had a scott mtb with a rear hub motor and sla batterys on the rear rack it was very heavy I bounced up a few kerbs and the rack snapped and 3 spokes broke and I welded the rack and then avoided kerbs.

I live in Denmark and rarely have this problem thanks to our town planners

Fair comment. I know Denmark, and if asked to sum it up in one word it would be 'Sensible'.

Trying it on the flat on a smooth quiet road first is best. Just do the smallest of front hops and rear wheel side hops to begin with, then gradually build up. When you've got them predictable on the flat, try over a low kerb and build up from there.

Trying to do small wheelies and stoppies also helps with learning control of the bike ends when off the ground.

Thanks Flecc. I tried wheelies once by accident - emergency stopping! I need to find a nice quiet street, nobody watching and some nice soft grass to fall on. At least I have a lot of padding
