In case anyone ever wondered about this I'll explain it. Also I sometimes refer to how I can travel several hundred miles on my 7Ah Batteries and ya wonder what drugs I'm on.

What you do is pull a cargo trailer behind your e-bike.

In the trailler you have 7Ah SLA or AGM Batteries

You also have an ac/dc Generator (4 Stroke Digital Inverter model). These are typically 1KW output and weigh 28 lbs and are very portable and not loud (under 80 db).

You connect your battery charger to the generator and to your battery pack.

As long as the Generator is on it is charging your wee small battery pack. The same battery pack your are using to power your motor.

You match the rate of Charge to the rate of discharge and you could ride non-stop to Vancouver if you could stay awake LOL

What the Generator does is give you the same distance ability as a Car or Motorcycle without having you spend a fortune on super lightweight batteries that you will still need to stop and charge them back up before continuing on your trip.

The Generator will cost less than a 48V Ni-MH battery, the Hyundai Generator is $450.00 at Wal Mart and at 28 lbs will be nearly the same weight as a 48V Ni-MH battery but with this set up all you need are (4) $15.00 AGM Batteries. So $510.00 total and a Trailer and Gasoline but you average 150 miles per gallon.

This set up is Illegal in BC only. That Province had visions of people using 2 stroke air polluting Generators.

CAUTION all... Joshua is advocating fuel that includes 30% taxes

Joshua,

If I'm wrong here I apologize. But wouldn't technically your setup make your ebike a gas powered vehicle? If the genny is connected directly to the battery than you're being powered by gas. I had thought of this before and asked around and was told it was illegal. There is however a loophole. The genny can't be connected to the battery that's powering the bike. However it can be connected to a battery that's not being used at the time. So basically two batteries. One in use and one charging and then swapped when need be.

Pretty sure this would be a series hybrid... generator charging batts and batts powering motor. The law is silent on how and when the batteries are charged

That is a genius idea. I had the same idea long time ago except that you can put the engine and power generator on your bicycle. When the cops stop you and ask for a driving license and insurance they can kiss your ass. I would use a smaller engine like 25cc or 30cc and not too big fuel tank because I am not planing to travel to Vancouver. Some people say that you are not green now and you are a polluter. Do these peole actually think that green is a reason to buy. It is the price. I would always prefer to buy a gas scooter but it is insurance cost and the license and the sticker. i like this noise from the TUBE but e-bikes are just cheap alternative. Lets think about it. How many people are going to buy e-scoot for 10.000 $, pay high insurance and you can not even hear any Bzzz or Brrr. That is why electric noiseless motorcycles are so hard to sell.

This idea gets floated periodically. There might be some sort of legal entanglement in fitting it into ebike legislation, but the concept is sound for a legal motorcycle. I have seen the proposal, but no actual production models, although Vespa/Pagaggio were kicking this around a while back I think.

I did find a production model, not sure where it comes from, maybe there are more out there. You could strap a small charger on your pannier rack like that guy who went from Ontario to B.C. and back did, and if you know anything about electronics, you could patch it into your electric drive/battery system. It would be an hybrid system, running either on battery, gas motor, or a combination. Add some LiFeO4 batteries and a larger geared electric motor, say about 1000 watts or so and you have a peppy machine. Most portable generators have a 12 volt charging port, just boost that up to 48 volts.

Here are some from Alibaba from China vehicles, I am sure if I kept searching there would be some more models. I think the concept is sound, not sure if it will catch on. You could always find a gas station if you are short of time, or a charging station/outdoor plug if more time to spare. It is the same idea as the Chevy Volt uses, a plug-in electric hybrid.

Well, I like them because they are green, no noise no pollution and they are cheap to ride :-))
