Re: Tough commute.

Smart move on Jasons part.

Over the years i've been mostly lurking here - no single person has more effectively comunicated the basic concepts of ebiking more consistantly, reliably and congenially than you have.

Re: Replacement motor axles

I'll draw up the axle. The chassis connection I havn't worked out yet.

Re: Replacement motor axles

For that 9C: Looking here : http://www.microbluebearings.com/pages/METRIC-SIZE-CHARTS.html it looks like a 6003 bearing will bring me up to 17mm journal size still fitting in the 35mm housing. the 6003 seems common enough; though is the extra 2mm enough to warrant the effort ?

Re: Replacement motor axles

Do you think it is possible to do a 9c as a single sided mount axle?

I have a few motors here that I'd like to use for a tadpole trike. But the front 2 motors really want to have a single attachment to the double a- arm suspension.

Re: R.I.P. le Béte

I'd try welding it back together with an oxy/acetylene torch and maybe steel plates sandwiching either side of the break.

Lace up a new rear wheel and keep on going.

lifepo4 cell group reverses voltage?

Just hauled out one of my bikes that has a 12s lifepo4 battery connected to a signal lab bms (red blinkey led type).

The first cell group is MINUS 1.5v, and all the others around Positive 3.2 - 3.3 v.

how can this happen?

Re: grunting at start - lyen sensorless

Well I can't discount the melted wire at the solder joint inside the motor possibility. But the reason I laced up this new motor (with bad halls) i had on hand was because I'd messed up wires at the axle just like you indicated. Xtracycle bag flopping over the unprotected wire at the axle.

duh.
