Alltrax Controller For The 20.0

[juanroberts]

I had Paul Master replicate his build on my 20.0 and it rides like a dream now.  I had bought a first generation 20.0 that was unrideable. I even got a new controller from OSET and it helped, but still was not any fun. Paul is known in our trials club as the EcoTrials guy because he made an electric trials bike from a Montesa a long, long time ago.  Then he did it with a 20.0 about 2-3 years ago.  He uses an Alltrax controller that can manage huge amounts of current (designed for a golf cart) and is programable, in tandem with a Magura throttle.  The mapping is so tame and predictable off the bottom that I can perfectly control and balance on turns now, and it ramps up to full power in the last 1/8 of the throttle which allows me to do zaps, go up stairs, etc.  I am using EarthX batteries despite their limited capacity just because they have management chips in them.  What can I say, my son burned the last set by leaving the bike on, and the EarthX are pretty foolproof.
