weelie problem, I can't accelerate full power!

[John in CR]

I use throttle regen with my Lyen controller, so your "awesome idea" is what I use on a daily basis. When I let off the throttle, regen braking comes on at the point where throttle would be just coasting. The amount of braking force increases to full force as I back the throttle to zero. The regen braking cuts off below about 10kph, so now I only use by brakes for stronger stopping or to come to a complete stop.

Sensored controller I presume...

I don't see why the sensorless version wouldn't work the same. It lacks the confidence inspiring feel of the throttle on a gasser, but I'm sure electrics will become more refined in that regard. I wonder how the throttle feels on those multi-thousand dollar ebikes. I bet they miss the mark widely too.

On the little race weight bike I built, I can report that the throttle regen saved me from ending up on my back multiple times. I did make a half-a$$ed effort for a few minutes to ride a wheelie, but never came close. I think a current control throttle would help.

Hey all, I got some video of the second run with frame mounted battery and seat moved front. Not impresive really I ordered some video sunglass, to make videos of my tracks, they are really beautifull ! I need to up the current limit as well

now that I'm getting used to the bike, I should be able to ride it harder

How are the video glasses? Where did you get them? I saw plenty the same on ebay for about $20. http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=280641467712
I see this video is with a different camera, as it has zoom.
I can't find any sign of anyone using them here, be interested to see how they look.

I found it was fairly easy and cheap to add a rear supension-arm to a hard-tail.

If you wanted to keep the bike fairly short, you can find a rear sus arm for a 20" wheel, and of course there are the more common 24" and 26".

It would make the bike longer and less wheelie-prone, plus adding rear suspension. If you decided you liked it better the old way, its easy to return the frame to stock.

weelie problem, I can't accelerate full power! ..but this one was too tempting at 50$ delivered

A full suspension frame for $50.. what you get is a short kids bike that wheelies easily. It's not as big a problem as being broke from spending $500 for a big FS frame though! I'm with you, I'd rather go for the $50 frame and have a blast. 8)
