Hi, I'm new here. Yes, I'm female (as you can see from my forum name).
I came here because I got frustrated trying to get a response from author Greg Davey of "How to Build a 50 MPH Electric Bike" before laying down the money to get his book. He's said nothing to me yet. And that's a big red flag to me. (I would never avoid response to customers if I were a technical author trying to make a buck.)
I want to make modifications to my 36volt, 14 year old EBike SX which runs like new.I'm a former scooter rider. I always got frustrated back then that I didn't have someone to help me learn how to service my own scooter, even though I lived in a PA valley FULL of mechanics! I guess I was just supposed to pay them money and let them have all the glory, and "keep my mouth shut", being a woman. Well, eventually my cheap Chinese scooter played out on me, and I wasn't able to ride it anymore.
Fast forward to today: I'm junking my old car, and looking for a way to increase this SX's capabilities to about 50MPH or more. I feel sad about losing my old car, but it's a source of pride for me to come here to want to learn as much as I can on on how to get this EBike more powerful. I'd like to make it my pet project, in fact.
It's harder for me to get my head around the electrical concepts, because I was used to making minor repairs to my car, so would anyone like to jump in and help me out?
Here's a video of an EBike being stripped down (good for viewing the frame, battery pack, control box and brushed hub motor) https://www.youtube.com/watch?v=vzbLFRIppLA
Will my project be a case of just getting different batteries and a different controller, or am I better off with all this plus a Hub Monster or Cro Hub as well to fit onto my vehicle? I am a heavy lady at 215 pounds, and the bike frame without its lead acid batteries inserted into the downtube is 65 pounds. With batteries - 75 pounds.
Note: right now, it's a real struggle for me to lift a bike OVER 65 pounds when traveling but I'm willing to accept any new parts as long as I don't have to lug this thing onto public transit anymore to help me get accross town!
Currently the new lead acid batteries only get me 3 miles down the road, at 15 MPH before they are discharged. And that's with pedal-assist too on this 7 speed bike. How embarassing!
It's not much fun. :|
