    Wife Hopper beach cruiser

    After sampling the sheer joy of my 24s GM 901 hub motor build, my wife decided she needed one. Okay, I actually decided she needed one. Due to medical concerns, it is a chore for her to pedal so her bike was sitting unused in the garage. I really wanted to use a better quality frame, but she...

    Cooling fans wired serially?

    Still working on my wife's bike, and I am looking to put her controller in a small, custom leather saddlebag (and her batteries in a saddlebag on the other side). These will be made by me, my first leather project! Since the controller will be enclosed, I planned on using four 40mm computer...

    25 - 30 MPH wife hopper?

    Hi all, So after taking a spin on my recent build, my wife consented to me putting an electric motor on her bike. Woohoo! Due to medical reasons she is not able to pedal much. Since the neighborhood speed limit is 25 MPH and she only plans to stay within the neighborhood borders (to my son's...

    Razor MX350 low on torque

    Hi all, It seems we are having an issue with my son's well loved Razor MX350, the older model with suspension and 350W motor. When I say "well loved" I mean it has seen a LOT of use over the last two years, a non-zero amount of time was my son riding two-up on it with a buddy... Lately I have...

    Front 26" wheel to "match" yescom rear

    I am still putting together a parts list for my yescom 48V 1000W rear hub build and am looking for a pre-built front wheel that will come close to matching the yescom rear. This is a picture from their website: Since my mom-and-pop LBS does not lace wheels and most estimates I am getting to...

    Dual brushed Currie MY1018Z questions

    Hi all, As I posted in other threads, I am currently working on modding a Mongoose CX24V450. The latest setup is 9s3p 15AH lipo with a 16T rear freewheel, max of 29 MPH, but I have no doubt that running at that max for very long would smoke the motor. I have been toying with the idea of...

    Parallel charging with 2 EP Buddy boards?

    I tried searching for this, but was not exactly finding what I was looking for... Currently I have a 9s3p lipo setup, with each 9s set made of a Turnigy 4s and 5s brick. I am charging with a Hyperion 1420i powered by a Mean Well 500W PSU. What I am currently doing is charging each 9s set...

    35 MPH cruise, 10 mile range, looking for tips

    Hi all, I am finally putting together parts for my build. First, a little history. My last motorized bicycle was a 66cc Happy Time with a 36T rear that would run 32 MPH pretty well and 39.7 top speed. After 400 miles, I blew it up (wrist pin bearing went, I knew I should have replaced it)...

    Mongoose CX 24v450 low speed and high speed options?

    Hi all, I have been lurking for a bit, but finally decided it was time to post and start planning the build. Last year I picked up a Mongoose CX 24v450 off Craigslist for $50, the batteries were junk and the forks were bent from when someone backed into it in the garage, but other than that it...
