What kind of brakes do you recommend?

[zzirrgrizz]

So I picked up this bike for $60 bucks from a neighbor and I also picked up a 2hp Briggs and Stratton motor for $30. I pretty much have everything all planned out except.....the brakes.

It does have coaster breaks but I will be removing the pedals anyways so it doesn't matter. I was thinking of maybe either a direct brake that pushes on the tire (not sure I figured this would be like the only way for it be strong enough to stop it, not sure though, btw I am very new to all this) or classic hand brakes that squeeze the rim with 2 pads. Which would you recommend for this project? The tires are pretty wide (about 2") so if I were to use hand brakes I would need to find some to fit around the tire. Anyways any suggestions/ideas are GREATLY appreciated

I'm not an expert but couldn't you use the kind of hand brakes they use on mountain bikes?

A disc brake? It would probably heat up really fast trying to stop a bike as big and heavy as that with a motor

Clutch brake(band brake on the clutch drum).
For this setup that's about the easiest, mind you how are you going to get the sprockets to mount to the rear wheel.
You have got alot of work ahead of you. Engine mount, brakes, gas tank ect.

Put a huge brake on the front tire and try not to flip over forwards. Just kidding, disregard this reply i couldn't help myself.

Problem with those is that if you throw the chain you lose your brakes, which gets much more likely on things where the chain travels farther like bicycles.

Front v-brakes might work okay on aluminum rims, but plastic rims will just burn your pads off. Can't tell what those are made of but they look aluminum.

The style of brakes won't handle the power. Ya sure no chain and won't have brakes, but this will stop and be more reliable to stop when you need it at speed.
I have some rim caliper brakes on my bike, but I don't use them when at speed. They are essentially used to stop for low speeds when just pushing around.
Simply put, They're not built for higher speeds, and heavier duty. Band brakes are.

Depending on weight of bike,rider and motor.. this may work.. its rated for up 20 250#..

I was watching Redbull rampage a couple nights ago and they use and abuse those bikes/brakes.They hit high speeds doing mountain runs etc.. I see no reason why a heavy duty mountain bike brake wouldnt work..
