Re: Lyen regl.: variable regen, maximal current from 5V

Ah, the old "I couldn't get it to work, so it can't work." conclusion. You were told the R12 approach wouldn't work, but bagged your head against that wall for weeks anyway. I stopped following the thread before you got around to trying a variable voltage divider on the current sense, so ...

Re: Lyen regl.: variable regen, maximal current from 5V

A couple of thoughts: I have walked down this path not too long ago. The short answer is that you can enable some change in the Regen during operation, however the application of the techniques described in changing value of R12 or the Current (Shunt) Sense create a very unwelcomed and compromised r...

Re: Who else is in the 5,000 miles or more in a year club?

Is the question about if we have ever ridden over 5k in a one year period, or repeatedly? The first year of riding ebikes back in 2010 (and actually it was about 10 months) I definitely broke 5k on the FWD. However I have slowed down quite a bit because I have either been away on business travel, or...

Re: Riding Leathers

If we are pedaling in any way shape or form, you will probably want synthetic/composite that is weather-resistant for our type of environment => mainly WET with spells of dry interspersed :lol: For racing, yes – I think it has to be leather, at least – that’s my impression from Pacific Raceways.

Re: Let's end the reliance on mechanical brakes?

Regardless, we still need mechanicals for when the electrical system fails.

It could also double as the holding brake on...
