My ride ....... "80cc" BMX

[Danjr1]

here's the pic of my nearly finished bike. just gotta sort out the chain and sprocket properly, remount the fuel tank so the outlet is the lowest point and to paint over the red oxide paint! then the fun of riding it!

You cut the top tube???

[Dave31]

Yeah I'd be a little worried about taking out that top tube completely. I would try to add something maybe two smaller tubes that you can bend around the motor on each side?

That down tube is not going to support the rest of the frame all by itself. Eventually there is going to be failure there.

[Danjr1]

Yeah I had to cut it to get the engine in. It's good quality (haro) trail bike so it's a tough frame with good welds so I'm hoping it holds out. It won't b going off road so fingers crossed. I may strengthen the down tube in future

[Finfan]

I'm afraid that with one good bump that thing will fold in half! The down tube alone just isn't strong enough. If they could build them without a top tube they would to save cost!

[Dave31]

Haro, Fit..... it dont matter that thing is dangerous!!

We do not want to see ya get hurt, I think you need to make some changes there buddy.

After you fix the frame... you'll need a smaller rear sprocket so it can keep up with the big boys!!!

[Finfan]

Yes, but that down tube is a lot stronger than yours, and quite honestly I still wouldn't trust it! There are reasons those frames are made the way they are.

you Definitely need more support on there.... looks like you can weld fine.. as fairracing said.. I'd weld something from the top tube.. around the motor on each side...
