I’m trying to put together an electric bike, with parts from http://www.electricscooterparts.com/. I’m using a standard bike frame that weighs about 30 pounds. How can I calculate how fast a hypothetical electric powered bike will go just from looking at the voltages and amperages of the batteries/motors listed on the website?

Can you jump start a wheelchair battery?




I have an Invacare Storm TDX3 electric wheelchair but the batteries are dead. I don’t want to pay 0+ for new ones, is there any chance to use a portable jump starter for cars to try and start them up?

I am trying to power my 36V motor on my bike and i don’t have a motor controller or a plan on how to build one, any ideas?
Thanks….. Wait i just got a great idea! All I need is three switches!
S+-S+-S+- If each switch can only handle 12v and the batteries are in Series then I just put a switch in between each battery and flip them front to back so when the individual switches are acivated they are within their correct voltage.

Now-a-days we see many scooters and cars are running on batteries.
I would like to know howmuch it’s harmful after it’s life get over after 2 or 3 years?
Which chemical is used in batteries?
Where it can be disposed of after it’s life get over?
Is it possible to make it cheaper?
Is it possible to install battery machine by removing petrol or diesel engine in any scooter?

I recently posted a dead Razor standup electric scooter to local "freecycle" Yahoo groups. The listing stated the scooter would be free but new batteries would have to be bought at Walmart for . I had hundreds of local responses. I selected someone and they picked it up. Now it gets stupid.

I also have another scooter that is working great I want to sell for . For those that didn’t get the free scooter, I sent a message to them asking if they were interested. You won’t believe the responses! For example:
"I’m sorry, I can’t afford this scooter now"….then where was the money for batteries coming from if I gave you the free one?
"I cant store anything else in my garage now"…then where would the free scooter have gone?
"I want the scooter to have a seat"…the first one had no seat, why would you want it?
"my son is too young for this scooter"…but he wasnt too young for the free one?

So please help me undrstand where this type of ignorance and stupidity comes from?

What is the best scooter for me?




I am aiming on buying a scooter (or moped) soon. I don’t want to invest in a car. I think a scooter is cheap and convenient (just using it to get me from school to home). I do not know anything about scooters. I was looking a gas powered scooters and I might end up getting that (because of the speed), but what are the best and inexpensive ones out there. I also looked at electric scooters, but I would not want to charge the batteries every time I use it. I don’t mind paying for gas. Any advice or websites. I live in NYC by the way.
I have license too.

run in series. simple as you can with 2 lines for pos and neg going to motor via batteries and a throttle control?

I’m buying new batteries for an electric wheelchair and I have 2 choices 35 AH and 50 AH. Nobody at the dealership can tell me for sure what the difference will make. I charge the batteries everynight so if longer lasting is the difference then I’ll go for the 35 Ah which is half the price of the 50 Ah

How many hours will a wheelchair last ?




I take my uncle for a walk in his electric hover round, we walk for about an hour and a half then it dies and i have to push that thing home. Had the batteries tested they were great. Maybe that’s all they last is for about an hour ???

I am planning a trip to Oakland. The Amtrak is in Jack London Square. Is it feasable to walk (drive my electric wheelchair) to 23rd Avenue. My wheelchair runs at approx 6 miles per hour and runs on batteries that can last approx 3-4 hours going full throttle. : )

Electric motors?




Hello.

I want to build an electric motorcycle by modifying a road bike to use a pair of deep-cycle automotive batteries, or perhaps capacitors or something else entirely. This vehicle is to be built on the cheap, but I want it to have high (40-60 mph top speed) performance, fair acceleration, and good range. I intend to accomplish the latter by regenerative braking, which as I understand it, would be fairly easy to do by reversing the polarity (maybe not the right word) of a DC motor through switches.

Questions-
-Where can I find such a motor? Can I pull one out of junked appliances? If so, which ones?
-What’s the best way to store power? If I do use two batteries, should they be in series or parallel? What about capacitors?
-What’s the best way to regulate power draw?
-How can I be most efficient with the power I gain by regenerative braking?

If possible, please provide links, or, preferably, a circuit diagram. I’m not really happy with the diagram I made.
