What stretch frame to use?

Postby Botsu » Mon Mar 05, 2012 3:03 am

This is my first posting, but I have been a lurker for a long time. I have all the components figured out to build the bike, except the frame. I want to build it on a heavy duty stretched cruiser frame. The one I found, I don't know who makes it. Thanks for any help I can get. This is the style of bike I am going for.

Where are you located? Aussie Jester is selling his cruiser frame:

NB: If I had the money I would buy Kim's frame, just so I could put a big hubmotor in it, and then I would constantly post ride videos talking about how much better it is with a hubmotor in it.

Pro-tips for noobs: Avoid BMS Battery like the plague | Charge RC Lipos to 4.15v, stop discharging at 3.5-3.6v | Use torque plates/arms! | Rear mounted hubs are always best

That sure looks like a full on custom frame to me. Wherever you are, got $2000? There is a good frame shop in Phoenix AZ if you are in north america.

Look at where the bottom bracket and the rear axle dropouts are. When the frame dips below that level it reduces the ground clearance. You need that ground clearance a bit more on a stretched frame than with a normal wheelbase.

There can also be differences at the rear dropout area that could affect how well a rear hub motor and/or torque arm will fit.

[EDIT] Some of the Basman frames aren't as much stretched as they are feet-forward. Is a long wheelbase stretched what you are wanting?

Are you a shill for this place that has a demo website up?

Are these louvers pointing in the right direction for a "speed" bike?

Thanks for the replies.. I am going for a long wheel base. I live up in seaside, OR. Have lots of areas to cruise plus with wide enough tires I can go out on the beaches. I tried to click on that link but it didn't work. What shop in AZ makes frames?

I'll dig for it. I don't remember the name off hand.

Arggh. Not finding it right away. Quite possible there are custom frame builders closer. I looked at the Phoenix yellow pages, but they might be in a burb. They were specializing in gas motorized boardtrack frames. I was hoping they had an ad at Motorbicycling forum. You might ask about frame builders over there.
