Parts?

I'd like to build a couple more bikes in the same configuration as mine, but can't seem to find the freewheel hub for the rear wheel. I can find the mount, motor, harness, controller and throttle, but no freewheel hub. Anyone know where I can get one?

No but if you find out let me know I would love to build one.

Hoi Deacon! From the looks of it and after much searching, I've come to the conclusion that it's simply a 21T or 22T BMX or single speed freewheel. Most are 14T to 21T, but there are the few with 22. Prices range from under $10 to over $80. The thing is, they're out there and can be had and can probably be found at your nearby bike shop.

Check out Freewheel +++ Best Bike Prices from QBike.com to see what they are.

Now to start getting that list of parts going.

Your bike may not be an E-zip per say, it could have been a Currie USPD kit or something. The motor cost $100 the batteries cost $80 for a set, and Currie quoted me like $50-60 for the rear rim with the left hand freewheel. And by time you get the controller, little button that kills the power when you hit the brake and all that stuff. Not to mention the aggravation and time to sort it all out.

You could have just bought one of these for $300: Walmart.com: E-Zip 2008 Mountain Trailz Hybrid Electric Bike: Bikes, Scooters & Skates I paid $400 when I got mine.

All the electric components can be found here: *ElectricScooterParts.com - Visit the Electric Scooter Parts store.

I was looking at TNC that Deacon pointed out. TNC Scooters (Scooter Sales and Service)

They got some pretty decent pricing on just about everything I'll need.
Only thing is I didn't even think about the freewheel being on different sides. I'm going to ask my local bike shop if it can be switched around or if they can order left side freewheels. It's gotta be something simple.

I really don't know which kit I have since I bought it already installed on a Next mountain bike. None of the mentioned companies uses this bike and the kit seems to be no longer available. Couldn't find it on the Currie site.
That's okay, though. Since I found sources for whatever I need, a kit is no longer necessary. I won't even have to hassle with all the wiring, since all that's pretty much available as well. Only thing is I may have to lengthen wires depending on the application. If all else fails, I already have a set I can clone.

Btw, part of the harness is made up of a computer power cord and receptacle.

When you get it under way how about some pictures with directions. I really would love a do it yourself e chain drive kit. One that isn't 400 bucks

Unfortunately Currie doesn't sell the USPD kits anymore only complete bikes. If you don't like any of the frames they offer you can move everything over to one you do. It would require a little welding. There is a tab ( guess you'd call it) on the chain stay that the mounting plate attach's to.
A year or so ago I was researching LH freewheels. I think this was the best site I came up with. Staton-Inc motorized bicycles, bike kits & gear drive kits. There could be better.

I must have been dreaming or somthing because I could have swore I saw an E-zip call the "urban cruiser". It was jst what it sounds like, an e-zip with a cruiser like frame. It was just the other day now I can't find it. Not a dream just found it. But the price is a nightmare!! Amazon.com: IZIP URBAN CRUISER Electric Bike: Sports & Outdoors

veloman at the site which must not be named did a good DIY elec chain drive kit.

Looks like the some prices are better at TNC.

You only need a freewheel with the Currie motors because of the internal gear reduction. All geared motors need a freewheel. veloman used a rear sprocket similar to the Chinese kits. But the teeth was different than the Chinese kits to match the motor sprocket teeth.

Hoi Ozzy, thanks for your input. Yeah, the ebike prices are getting up there and it seems there are only hub kits being offered. It's the reason why I decided to put my own kits together for my family's bikes.

For me, being way out here, it's more affordable.

I'm not up to par on gearing yet, but I understand the need for the freewheel with a geared motor from setting this rig up. Darned thang only turns one way. So does that mean I can run a chain drive to a static sprocket, like the 2 stroke kits, from a direct drive motor? That would open up more possibilities, yes?...like cheaper motors.

Hey Deacon. Just so happens I gotta go to the hardware store to order a countertop today. The bike shop is in the same parking lot so I'll be stopping in to ask about installing a lefthand freewheel. Will post their response later.

Btw, took the bike out for it's first commute today. I got a good laugh as there's one hill I hit 20 mph and the motor refused to kick in until I was part way up the other side and had to start pedaling. With pedal assist, I managed 15 mph up that hill.

On the way home, I threw the chain a block from work while shifting for pedaling on the flat. I had to motor it the rest of the way. Hit that hill and it managed to go 7 mph with no pedal assist. Got home and had plenty of juice to spare. Prompty put the battery on the charger and found out the chain came off because the highest gear was way out of alignment with the front sprocket. The rear wheel and cassette is from another bike. So I readjusted the derailleur so it eliminated that gear. Tadaaa. No problemo now.

I ran a test bike with a bolt on sprocket from a motor bike kit. It worked just fine except I kept throwing the chain for some reason. I was not using a geared motor though just a scooter motor.

What I think would be cool would be to mount a coaster brake wheel on the front of a bike and then an emotor onto the axle and fork where the brake would attach. Then run a chain from the motor to the coaster brake wheel.

You would have a nice front wheel drive with a free wheel already there.. I think i will do that. I have been looking for a new project.

deacon · #10 03-23-2009, 05:56 PM

Well I had a front fork from a 20" bike laying around... and I had a rear coaster wheel from a 20" bike laying around. So I ran down to the shop and guess what they will fit just fine.

Now tell me will that geared motor run either direction or only one. If only one which direction clockwise or counter clockwise....
