Garthe, where do you ride in the Valley? I'm out in FJ, Superior and TM all the time with my buggy.

That's my biggest problem, I don't ride my Montesa very much at all. We just had our Second Son six months ago and things are starting to settle down. My wife and I sat down yesterday and looked at the CAT schedule for this year and we're going to try and make a good portition of the Events this year.

My other problem is my regular riding partners don't ride Trials bikes...

BTW, I also have a Cota 315R, of '99 vintage. It was pretty banged up when I got it, but since it's my first trials bike and I'm far from being a connoisseur, I'm not too picky. I've only taken a couple of classes, and done one competitive event last year, but am thinking this hobby is going to stick.

I used to compete in New England Trials when I lived in RI. Then I moved to Coloardo and bought it from my friend who is dealer in RI. Now I'm in AZ and want to ride Trials again..

Howzit from South Africa Montessa fans.

I have an old 98 Cota that I ride in the Northern Regions Club trials down here.
Tough as nails and if I ride properly I can beat my mates on new Beta's ;)

Pics to follow.

electric cota

Hi,
I have been competing on my electric trials bike (made from 2000 315R) for the last three seasons with the SactoPITS club in California. I have been trying to upload a couple of pictures, but all attempts fail. I even tried down loading one of the pics from this thread, but when I upload, that fails too. If someone can suggest a solution I could try again.

Electric bike has a Perm132 motor, Alltrax 7234 controller, and custom 72V 11ah battery. It weighs about 175 pounds. Recent improvements include a power selector switch (100, 90, 80, 70, 60, 50 %) on handlebar, clutch lever operates rear brake. Last year I modified the frame to allow the battery to sit within the frame instead of resting on top of it.

Check out some videos on youtube (early lead acid version, plus later lithium ion version). Search for ecotrials.

Welcome

You can fabricate an electric trials bike from a Monty but can't load photos. Just shitting you a bit. I would like to see it. See how too on using snapfish.

Very cool.

I imagine it must feel very odd to ride w/o clutch, since modulation of throttle and clutch is so ingrained in anyone who rides trials.

I have hard time imagining, learning curve aside, whether absence of the clutch is a positive or a negative development. I understand that with the electric motor stalling is not an issue and starting does not require a clutch. But what if while balancing you wanted to let the bike roll forward/backward an inch or more? Is the motor circuit open at closed throttle to allow freewheeling? Can the throttle go negative to propel you backwards? How does it feel?

PS: One more question. I also wonder whether the proverbial "electric" nature of power delivery is a good or a bad thing for traction. From flat tracking and road racing, we know that lumpy power is preferable for better traction/feel/control, at least in some circumstances. Have you experimented with artificially modulating the power delivery? Since it's a DC motor, you are probably using PWM. What if you overlaid a lower frequency harmonic on top of that? And maybe even allowed for adjusting its waveform and frequency to suit trail conditions. Just a thought.

Hmmm, that bike looks familiar. I wonder who owns it?
