Re: Fat tire speeds

It depends on the tire rim combo. The first 4in pedago fat bike had a hard time keeping the tire on the rim. The tire with the spider design was really bad. But pedago use the cheapest of cheap parts as the rule.

Re: Motor and Controller Power Matching

A motor also makes heat when it luggs or Troggs. Its making heat in sand and going slow in thick mud. For the most part. This gets magnified when you over volt it or over amp the motor .Do you have a 350 watt geared motor ? Geared motor can hoer heat longer or quicker than a 28mm dd motor.

What voltage are the cells now ? Are they the same voltage ? Only parallel and then drain cells if matched voltage. 180ah is a lot of energy.

How'd you pay for it ? Make a complaint have them send you another motor they may just have you keep the first motor that they sent you and just send another one. Squeaky wheel gets the grease.

If I had and empty battery box I would take it to Bolivia as they have a big supply of lithium can you smoke lithium AR does lithium just smoke AKA fire. Yes I don't think it's the lithium I kind of bet on Cobalt and magnesium is the best fire starters.
