Removing 2 tubes from Dyno Gt Frame !!??? ....will it hold ?

[chain]

Hey all . Ok I got a Dyno Gt Deuce . I just got a Sachs Moped tank that will Look and Fit
Awesome ....if...I can remove the 2 rails that attach after the weld In front of the seat post that connect
to the front down tube . Just not sure because I see a lot of bike with out these rails so I think it should be strong enough
Any thoughts ??

I would have to suggest finding a frame not as sought after as a dyno

Those twin tubes are part of the cantilever. If you remove them, you'll likely make the rear end noticeably more sloppy. It'll "wag" under power and/or in tight turns.

You might be able to get around that with proper bracing, but I have to agree it'll be a real shame to hack up that wonderful frame.

Hey. so what makes you think that? I looked at the girls model and the seat stays end at the seat tube . Also most bikes dont even have those extra center bars . I will be reinforcing the frame with welding it before the seat tube . I relies a lot of Dyno lovers will hate me doin this but I think it will work . LOL man a lot of people don't want me doing this to that bike just cuz of the bike lol .

The open frame aka "step-through" versions of bicycle frames have nowhere near the torsional rigidity of closed frames.

I've experienced this first-hand. I've never motorized a "girl's bike" but I have pedaled many miles on a wide range of bicycles and tricycles.

Cantilevers on frames contribute to how the rear end reacts to riding surface. Weak cantilevers have been known to snap a few inches behind the gooseneck.

You want to remove most of the cantilever? Go right ahead. It'll probably be another bad idea in a long string of them that pop up on these forums.

Dam it I hate when people .........Make Sense .....when it don't agree with my idea !! I guess I still think most don't have that cantilever frame like bmx bikes and such... and i'm only riding it on flat road really . My jump days are over .

Good lookin bike, and good choice to not butcher that frame. I'm trying to get a in frame tank from Ghettobikes for the two moto glides I have, But so far no returns to my e mail requests. Guess they are really busy. The only weak spot I have found so far on this frame is the welds where the kick stand attaches to the frame. I had to re weld it and welded a gusset at the front of the mount 45 deg. to the bottom of the frame to keep it from wanting to rotate forward. It will be a lot easier to beef up this connection before the bike is built.
