Cyclotricity Kit : In-Line Brake Sensors

[sdrakey]

Hi Guys,

I have recently got a Cyclotricity Kit for my Kona Explosif 2001.

Its got hollowtech cranks which dont have much room for the pedelec sensor, so after reading other posts I think I am going to mount the magnets on the smallest chain ring and then mount the sensor on the bike frame.

I spent a while filing down my SID suspension forks droputs only to find out that the dropouts are mounted at the mid point of the forks and so the clearance isnt enough to stop the motor hub touching the fork legs, so will need to get some new forks that will accomdate the hub ( any suggestions they need to be ahead set compatiable suspension forks ( nothing expensive ) ?

I have some Avid Ti brakes levers and dont really want to loose them for the ones that came with the kit, but the kit ones have the electric brake sensors on them. So my question after the ramble is what is the best method or place to buy in-line brake sensors ?

Thanks

Simon

I've got a pair for £15 including postage. If you want them, send me a PM.

Hollowtech cranks are the easiest to fit a PAS sensor. You fit it in the left side.

Remove the BB completely. Chuck a couple of the spacer rings that sit behind the bearing holders. Chuck the internal spacer tube between the bearing holders.

You now need to reverse the sensor from its bracket. Unscrew it and mount it on the other side so that it reaches forwards instead of backwards.
Fit it behind the bearing holder on the left side. Insert the right hand crank and spindle. Clamp the magnet disc between the left crank and the bearing holder.

Finally, check that it works in the right direction. Normally you have to flip the magnet disc when fitting on the left side so that it spins in the opposite direction to that indicated. You can check befor tightening the left crank arm, and if it works when you pedal backwards, you need to flip the magnet disc.

Rock shox SID's? I think you'll struggle to find something of similiar quality that will work.

Have a look at the Suntour Raidon forks - they have the drop outs on the inside so should be ok. Not near SID quality though - but better than most of the other junk on flat pack bikes.

Anyone know any particular forks that would be good replacements for the suspension forks. Was thinking either allow or carbon forks. I presume they would be lighter than the suspension forks, but would theyvbe strong enough ?

I wouldn't use carbon fibre forks. Too risky! if they break you land on your face.

These look nice, just not sure if the hub will clear the fork's rounded dropouts.
