Right, so I bought this cheapy bike computer from sainsburys.

Can't really see where I can fit it to one of the rear wheels....

Any tips? I need to mount the magnet and the sensor and then run the wire to the computer somewhere. I think a few people on here have done one before, so lets hear the secrets!

I think i remember seeing C5 martin had one on the back wheel, the magnet was glued to the metal bit thats on the rear brake drum , and the  sensor was fixed to the bar that runs round the rear seat.

There were some pics of it on Martins site, but i can't see them now.

Ah brilliant, I was looking for somewhere on the motor side.

Will try tomorrow and post some pics if successful!

Chas, i've just rana test doing almost identical setup to you have there, and it works a treat

however, now that I have propped the rear wheel up, it appears 'Dave' needs some new bearings (or the nut has been overtightened)..

Only had a chance for a quick look. The wheel definitely doesnt free-wheel too good :(

..might be worth investigating the rear brake adjustedment as well , getting it to freewheel nice and smoothly is critical for good battery range.
