Lt members are a wonderful source of info....


I was considering buying either an electric bike or a kit to add an electric motor to a bike.

I need a new bike anyway, and thought it would be good to be able to remove the device, so as to use the bike normally.

Have you any experience with these options?

Any help will be greatly appreciated.

Thanks.

While not electric, this technology looks VERY promising:

RevoPower

Its an replacement front wheel with a small engine encased in the actual wheel. The only additional part on the bike is a water bottle style gas tank.

This does look cool, but:

It's not on the market yet

I need to make a 5 mile run and back, could easily plug in for next day

Not sure I want to carry fuel


I do thank you and will keep this in mind, but alas it seems to be vaporware right now.

how about these?
a real one i built and had a lot of fun with. the knife switch, while real, was just a spoof.
it surprised me that most people didn't know what it was.
my latest one had 210 "D" size NIMH cells connected for 36 volts and a gasoline generator for an emergency "get home" unit.
i called my "lowbrid"

Thanks. Great name.

I remember you telling me about this, but I didn't want a dedicated, single-use bike.

Heinzmann makes a good add on kit.
There are forums about this area.
There are electric bikes that can be pedaled as well.
There are some motors that drive through the chain so you have gearing.
The new Lithium air batteries look good.

I think if they are good electric bikes, they are a bit heavy to pedal alone.

I like the idea of an external motor that drives the chain myself.
I'd be willing to give up the pedal option for the gearing and design.

Not vaporware, check out the videos on their page. I'm not affiliated with them at all, I just like cool stuff. :D They did a spot on Invention Nation, which was more about green ways to do stuff than inventions in general.

I also can't wait for The VentureOne to hit the market.

What you need is called a hub motor, pedal or power as you need.
look at falconev.com for more info
Thanks, I will today.

Here's one of my favorites... I Swiss Flolding Mountain bike with electric motor. Full size, take anywhere and looks clean.

Take it in your car, or on a plane with the optional carry case
While this looks extremely cool, I don't actually want a dedicated elect bike, or a mountain bike.

I do appreciate your help tho.

How about a gas motor for your bike. Here's an example form eBay (current bid $132): <eBay Motors: 48cc MOTORIZED BICYCLE KIT MOTOR BIKE ENGINE MOPED NEW (item 310053358123 end time Jun-03-08 19:00:00 PDT)>. It's pictured on a funky bike, but it can go on about any normal sized bike. I saw one on a bike at the gas station last summer. The guy riding it was having a blast, and he said it hardly used any gas at all (it's a 50cc engine). Pedal to get it going, and you can let the motor do the work or keep pedaliing...

A major difference in some designs is the sophisticated motor controller on some designs, probably a pulse wave modulator.
The Prima L'Eco seems to be good quality but has an on/off switch instead of a controller.
The better design costs more, works better.
Heinzmann and Tidalforce use the more advanced design.

Some are also very noisy.
Heinzmann has been recommended to me as a quieter type.

Matched battery sets cost more, last longer.
You can always add more sets and better batteries.
A good charger makes a difference, costs more.
Some battery types need a good one, more than others.

A friend added larger wet cells to his bike.
It's heavy now, but has about thirty miles range, and for minimal cost.

Also some of the smaller packs are almost hidden, disguising the electric part.
This can be a plus for theft avoidance.

Thanks! Yes, Heinzmann has a good rep. I will also check Tidalforce.

I appreciate this info a lot.

i was using curtis brand PWM type controller.
it has the capability to field curve modify however you want to as well as current limit, etc.
of course, this was using a common shunt wound dc motor.
it WAS quite heavy.
curtis makes some good stuff at reasonable prices.
if someone is capable and serious about playing with such, my stuff is available.
i've gone to turbine, hence the youtube thing.
