Yes Picowatt,

I will be able to also adjust the camber from the frame also.

I just got my steel in today, using 1"x1"x1/8 square stock for the (4) A-frame.

Hi Mag,

Thanks for the input.

This is a test design look before I start doing welding on the front end a-frame and steering.

Hey tommy

Watched the vid. Looks good.  ;)   About the soaking of the wood. Just use thinner ply and bend it, then glass it. if you soak the wood to bend it, most all the water needs to be gone from the board before you glass it. If the wood gets warm or hot(resin curing, sun, etc), the water will expand and possibly delaminate the resin/glass from the wood, cause bubbles, etc.

Some other tidbits about the motor wheels...

if you ever take one apart, make a jig to separate the armature from the drum. The armature is the winding holder, stationary to the axle, and the outer diameter of the drum has the mags. My motor, 54 mags, little curve to them, about 1inx1/2inx 1/8in.  But all of them together have some serious pull on that armature. So a jig that separates them is a big plus. The biggest issue is the mags breaking if something goes wrong during manual separation. Lots of shims, one after another to lift all sides a bit unevenly, pain in the butt. And pain in the finger that happens to get caught in that bear trap.  Pulled mine apart to replace a bad hall sensor. There are 3 of them for timing. They are embedded in holes in the outer diameter of the winding cores to detect magnet positions for timing. I moved mine over about 1/16in to gain more bottom end. My plan with the arduino controller will be to add delay to those pulses from the halls to change the ratio of top speed or more torque. This will give the motors the best of both worlds. My first kit was a brushed Wilderness motor. The brush holder had slotted mounting screw holes for the same kind of adjustment. But that would take a mechanical deal to be able to adjust those while riding. So I figured with the delays on the halls, its a piece of cake to adjust on the fly.

The wheels that the motors come with are generally pretty much stronger than normal bike wheels. Spokes are fatter also. So dont get concerned about lots of weight on that rim. Chinese, but beef. Just check for loose spoke nuts once in a while. You wont know one came completely loos till it falls in the rim and jingles around. The rims are real stiff. So if a spoke becomes loose, the wheel wont wobble or seem bent to the side like a normal bike rim. So best to check them here n there. broke a lot of spokes on the trek rim. Hitting bumps and holes in the street at 25mph at a total of 300lb, snap, snap. Sidewalks are even worse at times.

Dont know what tire your using on the motor wheel. I recommend 2.0 tires. Adds a little more cushion to the ride. And looks better. Beefier. Razorbacks are  very resistant to puncture and flats.  Like 50 bucks but worth it if you dont want to fix flats pretty much ever. I go with bontrager street 26 2.0.  Last a long time and rare to get a flat. I learned my lesson. Was doing 30mi a day to work for 3 years. 1 day I had 5 flats. FIVE!!  UGH!   Just fixed one and 1 mile ahead, PSSSSSSssssss.  lol   About 38 bucks each. Worth every penny.  Also, for the tool kit, they have co2 cartridges to fill the tube.  Fast and on your way.  The little pumps. Over 200 pumps and not up to 65lb.  I dont mind a workout, but gees. Large cartridge will fill close to full. Got 3 in my kit. Havnt used one in a year. ;)

You can make a kickstand thing to raise the rear and also on the front for repairs and even maintenance. Just ideas for ya.

Mags:

I like your thinking on this.  Very good ideas.

As far as I can find out, KY has no laws on electric bikes.  Now, what would be the difference between an electric bike and an electric motorcycle?  I would guess...speed.  But, I find nothing saying anything about this.  The 50cc motorized bike I built complied with all of the laws here pertaining to motorized bikes.  Well...almost all.  Speed was supposed to be limited to 25 mph but I could hit 36 on a flat road.  The law said I needed a step through frame (think scooter) so I built it using a girl's bike.

Has anyone done an electric bike using a trailer for the batteries?  I mean, a small bike trailer could hold several car sized batts and/or even the motor.  I have seen tube videos of guys using trailers for gas engine bikes with larger engines than the law allows for but, the law seems confused on the trailer bit.  Four 12 volts car batteries on a bike trailer with a nice solar panel on the top could power your e-bike for a long, long time.  Otherwise, build a battery pack out of 18650 li ion cells.  (Like 50 of them)  I could make an e-bike go over 100 miles/charge easily I believe.  You could even use 2 motorized hubs on the trailer and leave the bike stock.  Batts and motor in the trailer.

Sorry Tommy...

Design is looking good and I hope you raise a lot of money to make a lot of them.

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.

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.

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?

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.

The Triax was my first ebike. $169 at walmart, $300 for 36v wilderness kit. The trek bike was $350 new on sale from $450 due to new models coming out, and the kit was $600, batteries and all 7 years ago.  Bags and lights extra. I recommend building your own always. For the same price, a prebuilt is usually lower quality.

Hi All,

Ok I just finished the A-frame for the front steering and shocks.

I decide to go all metal, it's cheaper then fiberglass.

Hi Telecom,

I have be thinking of building simple air shocks, getting a 4" water rubber hose.
