E-Trike Kick Starter Project.

Oh yeah, the trailers.  Yeah that can be done. Look up bicycle trailers. They have them for kids, and other uses. Pretty simple and neat hookup to the bike. Heck, I could put enough sla batts on that to go 100mi.  LIPO probably 200 or more mi.

Hey Bill

Its a federal law.  Some states or cities may have their own laws also, Like I heard that S.C. allowed 30mph. But that was hear say.  In cali, you can have higher speeds up to 35 with registration. Tag I suppose.

The gas motors work pretty good. Cheaper than electric for a kit usually. For me the drawbacks are noise, cant bring it in the apt due to fumes. And can make you smell like you have been using a leaf blower all day. lol. The hub motors are very quiet. Some have internal gears that are noisy. Some are chain drive and noisy also. But the motor like Tommy has, like mine, there is a hum, but pretty quiet. Wont wake the neighbors. Or a baby. lol And the low end torque is incredible. Ya have to ride one to gain full appreciation, There is a stigma to electrics for some reason. A lot of people tend to think of the little electric cars kid ride. Like 3 to 7 mph. But once they take my bike for a spin, they seem to take a long time to come back.lol But then they are amazed and say, I would have never known till I road it. I have 3 bikes. Total miles of about 25k. Lost count. Trek has about 15k. Little walmart triax with wilderness kit about 6k mi. And the tidalforce m750 about 5kmi. I still sold.

Electric is awesome. My fiero will us a dc motor, 9in dia, 15in long.  Will beat a normal fiero all over the place. Whats really cool about electrics also is that you can exceed the typical constant power input over 10 times in spurts. So the motor I want is a Net Gain Warp9.  like 18 hp at 72v rated. But you can give it up to 300v. Figure how long do we really need to be accelerating, then we only need about 16hp to keep the vehicle at 65mph. Some vids on YT show guys with evs using this motor and its just plain sick. 72v wont get ya very fast. 40, 45 maybe.  So I want to run 144v. Just transportation. Will do 70mph or so.

Would love to build hub motors for the fiero. Gota do a lot of thinking on that one.

Well one thing I think I know about dc motors is that the torque curve is flat.  In others words, if I am saying this right, unlike a gas engine, a dc motor has all of its torque at 10 rpm as well as 3,000 rpm.  I drive an electric golf cart every day at my job.  it is very anemic and only does about 16 mph.  It will not even spin the tires on solid ice, as we have had here all week!  But, the motor controller is programmed with an acceleration curve. (I spoke to the repair guy)  He said he can hook up his laptop and increase the top speed to 27 mph.  It uses 5 large 12 volt cells. (each larger than the big battery in my van) and the charge only lasts one full 8 hour day of patrol.  I am not impressed with it at all.

But, I could get into an e bike for sure.  Around here, as long as you looked like you were pedaling and there was no exhaust noise and smoke coming from the bike you could probably pass a cop doing 50 mph and they would leave you alone.  I looked at those hub motors before building my other bike and a single hub motor would have cost me more than I paid for my bike (new) the engine, and the drive system.  Then I would have to buy the batteries and controller.

Like anything else, the price is coming down so, I will take another look at these.

Can you pm me with a link to any videos you might have of your bikes?  I can send you the one I have of my 50cc bike, which I no longer have.

Never did any vids of the bikes. Can though.  Just found my pics

Here is my first bike and the trek.  Looking for my tidalforce pics. They can be found on the net also.

Also a pic of my speed control box. Top sw is power, bottom sw switches between a preset and full power.

Very nice.  Nice bikes there.  I noticed the hub was on the front wheel....does that make it hard to drive?

Bill

[Magluvin]

The front wheel drive does take getting used to. But it has advantages also.

Being there is no noise of a running motor, it is always possible to hit the throttle by accident when walking the bike. With rear wheel drive, it can knock you over or jam a spiky pedal into the back of your leg, etc.  The front drive will slip, but the rear digs in when walking the bikes. Yeah yeah, just shut off the switch. lol. But it will happen.

The other thing, when riding, front drive helps navigate tight turns and zigzags. Where a rear drive can push you over if you turn too hard. Its something you have to experience. The tidalforce bike is rear dr, so I do have experience between the 2.
