OCC Schwinn lokalike chopper E-bike

[Fly_boy_bc]

I am building a chain driven motor assist chopper bike. (O.C.C Schwinn Stingray lookalike)

For power I have a motor and controller from an Invacare Panther MX-4. The fellow at the store told me it Was either 1.5 or 2 HP...Not in that range but one or the other.

I purchased two brand new 37 AH 12V. SLA batteries and I am about ready to begin fabrication.

I have an OCC chopper lookalike and I have all the info I need to adapt it to adult riders. I have a hub adapter which is meant to adapt a sprocket for those chinese motor kits WWW.motoredbikes.com.

I am mounting the batteries in custom aluminum panniers which I am fabricating myself.

Tomorrow I will be getting a chopper style motorcycle saddle and low riser chopper handlebars. $60.for both not to bad)

I have several questions. All of them about the motor which really need to be answered before I can go much farther.

Firstly does anybody know what the no load RPM would be? Even if you just know about mobility scooters in general please answer so far that piece of data has eluded me.

Can I run this 24V motor at 36V. and get away with it?

Do I have to worry about the fact that the motor will be driven by the wheel whenever I try to coast? I have been planning to use a BMX freewheel rear sprocket as the drive sprocket so This would not happen but if I can avoid an unnecessary complication I will.

Motor: Pihsiang Machinery Mfg. Order code M3-9MNF-2A

This is NOT my bike this is the kind of look I am going for

A lot of those bigger motors run less than 10,000 RPM's, I don't know exactly what though.

I think you should be fine running it with 36V, just not for really long periods of time as it *may* cause the motor to get hotter than normal.

When you coast with the motor attached and no power going to it, you can short the motor contacts and it can act as a brake to slow you down.

What's the picture of the girl for? :confused:

I was under the inpression that it would be around 4000RPM

Thanks that's about what I figured

Yes but will it slow me down when coasting and not braking?
