I am 60 years old, just finished chemo and do not have alot of energy left. I was thinking of getting a power assist bike so I could get some exercise because the bike I have takes more energy then I have. I need a simple bike that will allow me to pedal, but will also assist. I have read alittle bit and probably the electric would be better then gas, for the speed and noise. But any assistance will be appreiated. Thank you.
Answer
There are two ways to go: A purpose built electric/pedal bike or trike or an add-on kit to a regular bike.
Electric is much more useful than gas, since electric assist bikes can still be used on trails (gas, even mopeds are almost always prohibited). Plus they are quieter, lighter, less smelly and, most importantly, more bike-like.
Consider a trike too, especially a recumbent. They are much more comfortable and easy on the butt. More stable (they can't fall over), you can carry a lot more (basket in the back) so they are more useful for errands and they can stop on a dime. The big penalty has always been the extra weight, but if you are planning from the start to use a motor assist, then weight isn't that big a concern is it?
Good luck. Biking is the best exercise in the world!

upgrading an electric scooter any advice?

I drive a 500 watt TaoTao ATE 501 and it only has a top speed of 20 to 21 miles per hour and only drives 10 miles per charge(I think) Is there any upgrade parts I can get for this scooter so that it can drive 30 maybe 35 miles per hour and get better battery life? I'm tired of being on a street legal scooter/moped and not being able to keep up with average city traffic flow. I hate being tailgated because I'm driving slower. I think it runs on 48 volt batteries and uses three of them. Not sure about the control box because its kinda hard to get to.
Answer
First you have to realize that those 500 watt electric scooters are really just heavy cheap electric assisted bikes. The TaoTao ATE 501 weighs about 200 lbs and that's why it's so slow. If you want any reasonable performance, you use the fold out pedals at least for acceleration, it also recharges the batteries slightly.
I suspect you have a 36 volt system with three 12 v lead acid batteries wired in series. It would be a good idea to have each of those batteries checked out separately. Lead acid batteries can be tricky and it only takes one to be in poor shape for the whole bike to suffer.
The most obvious upgrade you could do is wire in another three lead acid batteries in parallel. Nothing else would need changing but you would have to find a location to put the batteries.
The next possible upgrade is to replace the batteries with expensive lithium ion or lithium polymer batteries which are convenient because they are available in similar voltage levels. Their charging procedures are similar but not identical so you may be able to get away with not changing any of the charging mechanisms. The biggest problem with this is the cost.
A larger motor probably won't do you much good and may require custom fabrication of the motor mounts but you may be able to find a more powerful motor in the same form factor. In general, most electric motors can be operated at higher voltages with the only consequence being overheating of the motor and wires, the wires can be increased to thicker wires and you could try to get more cooling to the motor but this would really only allow you to have short bursts with the possibility of burning something out. Of course doing so means changing the battery layout and adding more batteries.
The best solution would be to upgrade to a proper light weight electric assisted bike but they run about $2,000 or more, roughly double what the scooters cost. Maybe find a used bike and put in a 500 watt conversion kit... At least with the bikes, everyone expects you to be slow.
The 500 watt scooters are not what I would call street legal, just exempt from regulations. It takes a 150 cc scooter to be freeway legal and a 250 cc scooter to actually be safe at freeway speeds and any scooter with more than 50 cc's must be licensed and registered as a motor vehicle. Those I would call street legal once licensed. You might be better off with a 50 cc gasoline scooter, those are usually exempt from regulation too. The old smoky two cylinder ones had a lot of power, about double what the new four cylinder ones have but even the new 4 cylinder ones would be four times the power of the 500 watt electric scooter. If you want to be environmentally friendly, make ethanol from rotten fruits that you get from the grocers for free.
