Question? If you bypass the discharge on the bms, can you moniter the battery voltage and watch to make sure it doesn't drop below 60v under max draw? This is on a 72v battery.

Don, Another great project . Can't wait to see it up close.

What's with that handicap sticker? It doesn.t apply to us that have too many head hits.

I can't imagine a ratio that low. How many amps are you putting to the motor at 6.6 to 1? At 5.7 to 1, my bike has plenty of torque to get around the track. Are you lowering the ratio to load the motor less? How many RPM's is your motor spinning? What top speed will you get at 10-1? Thanks, Bob

Yes, ASI. I do not have the knowledge to set up much on the controller. Very new to the E world. I will do some research and try to learn the proper functions to log data. Thanks Mark

I have a few questions and hope someone can help me out. Bike is running good and getting better. I am able to get 10 minutes of hard track riding. After that, the bike gets slower. I slow down and stop for just a minute. I do not even have to turn off the main power. I can go out and the bike...

The reduction shaft is adjustable making it possible to adjust the primary chain and use different size primary sprocket and countershaft sprocket

I have a chain reduction using 520 chain. the drive ratio ends up being 5.7 to 1. I am going to experiment with a couple different ratios and see what is best for each track we ride.

Thanks Jason, you made it easy for me again. Don rode it today and said he really liked it. It performed better than I expected. Just have the stock suspension for now, so it needs tuning. Will look for a little more snap but very happy. Updates when they happen.

I am riding tomorrow at Cahuilla Creek with Don. I'll get some pics and ask my sons to help me prove it happened. haha

Well after a year plus of working on the ECRF, it finally rolls on its own. I first of all want to Thank Don Cox for the patience, knowledge and guidance with my build. He has became a good friend and the first ride was fitting to be out in the AZ desert with him. With an ME1304 motor, ASI BAC...

Being an old racer from the twin shock era, lay down shocks were the first attempts at changing leverage rate. Not nearly as efficient as modern bikes, some of the last twin shock Maicos were quite good. Would they survive on a SX track, absolutely not but in reality can they be made to work for...

I am in the process of building a CRF250 E bike. I have done some ICE 500's and enjoy building different projects. A small bit of background shows I have zero electric motor, controller or anything voltage or amp related experience. I have been very fortunate to meet and develop a friendship...
