Help! Will this break anything?

The top of my engine head is making contact with my bike but will it mess anything up with the electrical components? Here's a photo.

Can we see a more expanded view with another set of pics.

I would like to see exactly what you did building this to be in this position...I think you may have a little more to worry about then just your electrical, things like stability and avoiding a death wobble comes to mind if you cut your frame like I think you did.

Here's the whole bike, still working on it.

OP, with all the stress now going to be on the bottom tube it will fail at the BB or the head tube. Disaster awaits, please rethink that!

I think you probably ruined any stability that bike would have had as it is obvious that frame does not have enough room to even accomodate one of our motors properly...You chose the wrong bike for the job you intended it for.

Just like in house building, you have walls that are also supporting the structure, you can't remove that load bearing wall without causing structural damage to the house...It is the same with that bike, that tube you cut was part of the main support of the bike itself and will fail under motorised power rather quickly and you will get seriously hurt.

I am going to let others chime in on this since many are welders and many here can quote you chapter and verse what happens when you screw up the basic geometry of the bike frame like this.

Ah Thanks could you suggest any other bikes that would work with the kit?

Pretty much any decent beach cruiser style bike...I use the Hyper beach cruiser myself And only use the frame, handlebars, pedals, and the seat unless you want a wider one like I did...lol.

Robot or human?

Here is what mine turned out to be when I was done with it.

Here is the "tutorial" I wrote describing exactly how I did it.

Whats the best bike for a 2 stroke?

Were miles away, but I bet our side of the railroad tracks are pretty similar. Before I found cranbrook in trash, I picked up a 74 schwinn world traveler & a 74-75 schwinn varsity people were throwing away, was going to build 1 of them, but long skinny front forks were scaring me. They can be...

Here's my current build on a hyper.

I put a motor in a bmx. It takes some thought for sure. But it was fun. And sturdy.

A bit late to ask but how did you mount the engine? Or was it a bigger bmx
