How Do I Upgrade From Coaster Brakes?

I just assembled "The Dragon Lady", a twin-engined Raleigh girlie cruiser. It has a modified pocket bike engine on front friction drive and 2.2hp Mitsubishi engine on rear friction drive.

I have not run the bike yet.

It has EXTREME power and needs brakes to match.

The front fork has vee brakes, rear has coaster. I need to upgrade rear brakes, maybe eliminate coaster entirely.(I have had major coaster brake lockup at 25 mph.)

Is there any way to install vee brakes or the rear and freewheel the rear sprocket?

Thanks for help.

Thanks but that project doesn't work for me.

That topic should be titled "Coaster brake conversion to FRONT drum brake for motorized bicycles".

I already have good front brakes. I'm trying to eliminate the rear coaster brake and install rear vee brakes and freewheeling.

after two coaster brake hubs crappin out on me i bought a new freewheel single speed hub and and old school hand brakes and have been happy ever since. in my experience having a coaster brake is just one more thing that could posibbly crap out on you

i anew single speed freewheel hub and wheel would be the way to go and while your at it see about doing a rear disc break that would give you the most stopping power. I run 3 brakes front and rear side pull calipers on a duel pull lever and a coaster that doesn't get used much but is nice to have when it is wet outside

there is my two cents

I'm leaning towards Huffy and mike's suggestions of single speed freewheel hub.

mike, what are old school rear brakes?

Disc brake might not fit because I have 36tooth rear sprocket. That's for my next upgrade of Titan chain drive assembly and 2.2hp Mits engine on this bike.

sorry by old school i mean the calpier brakes that mount to a single centered hole in the frame or hole in the front forks plus they are cheap and work well enough not as well as disks but once you start looking a disk ready hubs the price on the wheel really starts to increase. the last bike i built had discs in the rear and honestly with a top hat adapter the sprocket went on like butter

i bought my brakes in a bag at the bike shop for $20 came with 2 handles (crappy) 2 brake cables and the "old school" calipers mike is write they just bolted to the holes in my cruiser frame. i had to hang the back one upsaide down but as long as the pads reach the rim is all that matters.

i did add a duel pull lever i think it was $15

Thanks, Huffy.

I have an extra front brake. I'll see if that'll fit on the rear frame.

If you REALLY want the best rear wheel brake, sprocket, and heavy
duty spokes package , then check out Ebay. Type in "direct drive wheel
motorized bicycle" and you will see what I mean. It ain't cheap for
$229.00, but it is THE BEST you can buy. After all how much are your
medical bills gonna' cost ya, when you blow thru a stop sign or light?
