Help needed! Dream bike build!!!

DementeDave said:

Hi guys! needed some help here. I've been snooping around this forum for months and I've finally decided to sign up and ask for help...

I want to build up a motorized dream bicycle. As I cant find a local shop selling the bicycle and engine, It is very difficult to ask for advise and gauge the riding position... Hope I can get some help here many thanks!!! OH BTW I live in Surrey BC, Canada and I am 5'8.

Here's my specs:
Under $2000
signal lights (turn left/Right and brakes)
Head light
4 stroke 50cc engine with electronic starter
rear FAT tire (did I say FAT???) ;p
Full suspension
disc brakes (at least front, best if both)
Bike frame and handle bar has to allow me to ride upright and my legs stretch foward
No welding involve

I think thats all for now...
Many thanks again!

Welcome DementeDave you are in the right place for building a Stretch Cruiser or Chopper with a Chinese cloned horizontal honda CRF 50cc type ATV / Dirtbike / Pitbike engine.

I'd suggest a Stretch Cruiser from Bicycle Designer or ChoppersUS, the one Bicycle Designer sell's has a square bottom tube which would allow an easy setup for bolting a steel plate to which you could then bolt your engine to, you did say you don't want to do any welding.

The engine can be purchased thru Gio in Canada, however I'd suggest buy a used Kids ATV and just scavenge the engine and components like wiring harness, intake carburetor, etc etc..

As for front forks ChoppersUS has the springer forks with disc brake, and Bicycle-engines.com has the dual drive heavy duty rear wheel with band brake ( not quite a drum brake ).

For more information please see the following members builds as they have built their Stretch Cruisers with this type of engine:

Both forum members above have included in the threads / post's for their builds what some of us call a Build List, which covers most everything needed to complete a similar build, where to buy the parts and other how to information.

Let us know if this helps you find the engine or frame for your new or first build?

DD, I don't know how you can mount the Chinese cloned Honda horizontal 4-stroke 50cc ATV / Dirtbike / Pitbike engine to a round tube maybe RedB66's motor mount clamps he use's on his Stretch Cruisers might work on a round bottom tube frame.

I'd recommend getting the Square tube frame Stretch Cruiser from Bicycle-Designer, since it would offer you the easiest way to mount the skid plate to the frame, and then just bolt engine to the
9 x 5 Motor Mount
Flat Engine Mounting Plate
9" x 5" x 3/16"
Heavy Gauge Steel
Slotted Mounting Holes skid plate. Skid plates can be sourced from Here's the Link: Motor Mounts BMI Karts and Supplies - Home

This can be done without any welding!

DementeDave, welcome to the forum. I'm in Ocean Park/Cresent Beach or south Surrey if you prefer. You may be able to use the tank on the bike as a gas tank. A lot of the fellas have a gas filler welded in and fill the tank with gas tank sealer to prevent leaks. That depends on how the tank is built of course. Getting away from some welding is pretty hard.
Check with Terry Blow on the forum and I think he is advertising in the sponsers on the side of forum. He sells Grubee 4 stroke kits and is just off the King George Highway in Surrey. He has built some nice bikes and will be able to help you.

Dave, his buisness is called Blow By U.

Dave, if your talking about the 4 stroke, Terry Blow sells the clone or the real thing.

16" L x 12"W x 9"T give or take 1/4" or so, not including carby, mounts, manifolds or chain clearances (49.5cc auto clutched three speed, electric start)

Dave, you can't register the bike. You have to be a recognized manufacturer who has has thier product inspected by the federal government then you can put a 17 digit number on it that is needed to register it.

E-bikes.ca, will put you in touch with the folks that helped me put my bike together. First rate operation. The're on Main St in Vancouver about 29st.

You can see my bike at "pictures by speedydick- photobucket" and the tread is on board trackers and vintage bikes under sidecars. Mick started the tread and then I kicked in. It's back a ways so you will have to look back a few pages.

Steve.

This may make it faster.

The first photos in the album are from when I changed it to a solid mount instead of being able to pivot side to side.
