Hi, Matt. I like your electric bike concept. Kinda more like a moped than a bicycle. I see you are not trying to add pedal power, which will simplify things. The one thing I am concerned about is the sprung seat vs. sprung rear axle. I think it will not be so comfortable to ride as you might think, and I urge you to mock up a prototype just to evaluate the suspension. It could be un-powered (gravity downhill power), just to check handling. The sprung seat could work if it was short throw and stiff. Just my two cents:., worth $.02

Reminds me of the girl that does bicycle seat testing for the CarTalk program. . . .Her name is Mia Certz. (say it real fast)

I see that prototype is a happening thing!!

Im working on the seat system now and so far its working perfectly. however Im re working it as the real deal does not look right. I have to make some adjustments to get the geometry right and look right. Yeah the springer seat does not move very far only 2 inches max and that would be a big bump to move it that far. It is designed to work with a seat that is also a suspension seat.
Im also rebuilding the steering the head as it has way too much sweep. Its not supposed to look like a chopper. lol. So Ive made some tweeks to sweep it back 5 degrees.
These are road versions so far, but I do plan on dual purpose version that will have a rear wheel suspension along with the springer seat system. The rear wheel suspension will be more for handling not so much comfort, but the two systems combined will offer a better range to soak up bumps.

Some versions will have pedals, it depends on what the customer does with this kit. This is not a full bike its a kit. Its up to the end users to source wheels, front fork, motors, batteries etc. Its just a frame system that will have about 50 different configurations. The steering head and the channel frame are the only parts each version will share. The seat system and the lower bracket;; there will be different ones that we will design and manufacture. Some lower brackets will be designed for existing mid drive units that have pedal systems built in. Other versions will be more specific to hub drive systems and designed for battery storage verses the mid drive motor system.
The current designs are for DIY custom motor drives built out of what ever you can make work. My focus is to use the cordless chainsaws as they have everything you need built into them and the motors offered are more powerful than existing E bike mid drives.

VE/B -1 coming together. I redesigned the steering head with much less sweep, steers much better now and is much more comfortable. First version of the springer seat is now complete and works nicely. It feels like my full suspension mountain bike I bought a while ago. The position adjustment worked perfect to plan I have it in the second to last position and it works very good for my weight but it can be made stiffer or lighter.
Moving on to the mag wheels next, and then hopefully someone will invest as I wont have any funding to take any further. The gasser company has completely flat lined and I dont see it making a come back. Its time to move on but I will keep the business in tacked but pricing will most go up significantly. Most I dont think realize the deal I was offering for the level of machine we were building.

if you want to run the bikes with out a licence you need to have pedals. dont matter what the bike looks like even that trail bike henry put up needs pedals. i dont know the american laws but here in canada you dont need a licence if it does not go over 45 kmhr needs 8o watt motors it can be 75 volts etc. most people in canada get them because they are licence free. any thing else up here needs a motor cycle licence to run. or in ontario anyway. that bike you show would need a motor cycle plate with out the pedals. but it looks strong. hope you the best with your vendcher

Thats up to the user and partly why its a kit. If its in a partial kit then its in the users hands.
Here in Michigan, it dont matter if it has pedals or not. If it goes over 28 mph it needs to be licensed regardless of pedals or not. If you have a pedal bike and you are caught exceeding 28 mph on the road they will give you a ticket. Otherwise just get an ORV sticker.

So for the rear wheel I found an old internal geared 3 speed hub. However I need to make it with the 20 inch rim. So Im going to CNC some spokes out of sheet metal to try and make it work. I have no idea if it will work as the spokes do a lot more than support the wheel, they keep the rim straight and true. Its just a proto so I think they will serve their purpose.

Also you can put pedals on it. This is my build, I dont want pedals, its up to you if you want pedals or not. You should read the full post on this concept. It can be built anyway you want.

ah so down there 30 aprox mphis the law i like that idea better because most people dont use the pedals any way and after a couple of years they seize and then they cut the chain . ha ha looking good . i have a bike licence any way i drive a 1100 honda. tried a electric bike at my sons but found them slow at startup i guess i am just spoiled. 0 to 60 instanally.

Now your getting it. This concept is to build it with better motor drives. This bike Im building now will scare you when its done. I plan to cram three or more of the chainsay motors in this thing. But to fit a broad market and make it DIY for everyone there will be options designed for specific drive systems on market. You just buy the parts and put it together. Doing a kit, limits my liability as the user is the one that built it.

okay i was telling my son about your bike he is the mechanic for the repairs in newmarket ont. if you want to talk to him he said he would be willing to that is his thing. he might be able to help as he is up on the newest thing motors batterys controlers etc. here is his number 1 289 926 6448. he might be able to give you some ideas or you him… he uses a log app for the repairs?

Matt, Yes I get it. Same thing that is done by the Experimental Aircraft Association members when they offer partial kits with plans. They build the hard to build sections, where you might use jigs and other tooling, or hard to get parts. The liability rests with the builder. Good plans with good instructions are key.

Here is the first attempt at the mag wheels. Almost but not quite as suspected truing the rim was a challenge. So I will revise this on the front wheel attempt. The plan is to make some cleats that will bolt the rim using the spoke holes. This will be a molded part with metal threaded inserted to bolt too. The the sheet metal spokes will bolt to this cleat one on each side. The mounting holes will be slotted so you can adjust tension from one side to the other to compensate rim alignment.

You’re a real expert, Matt, you have a good sense of design and a lot of creative energy.
Years ago, my brother also made a pair of electric bicycles on pedals …
-The battery is supposed to have 1kWh / 1kW of engine power
- battery price approx. 500 € / 1kWh
-have a good BMS

Once a customer buys a cordless tool, they tend to stick with that brand, because of the batteries. At least I do. So, with your bike they can leverage their cordless tool investment. Nice idea !
Just a thought; maybe a pusher for bicycles…
