finished the gravity bike ive been working on....so much fun and so easy to build...

does anyone else ride these damn things?

Do you buy a kit?

I've always been interested.

That thing is weird, cool though.

Decided to do some research... http://www.gravitybike.com

so its basically a downhill speed bike?

[ianFrom2004]

crass: they are almost like driving a crotchrocket(leaning and all) down a hill...except that they dont have any power(obviously)

i was at a downhill/luge site and saw a long video about those. they look pretty fun, but wouldnt it be really uncomfortable curled up like that? personaly i would like to ride something comfortable...like a longboard or a luge. anyways cool idea. probably goes hella fast. you should clock youself and give us some speeds.

there is something utterly stupid but utterly awesome about gravity bikes.

whaddya' think about cable-actuated disc brakes?


I'm just thinkin' if you brake for a long time the rims are gonna heat up quite a bit. A high speed flat can't be much fun.

I've seen rims that were worn through, to the point where they split on the sidewall from excessive downhill braking, although that was on a ski slope.

Brakes just get in the way, if youre a man you'll go for the hay bale.

Gnarly!
I thought this was a reference to DH mtb's, but this is a whole new (to me) level of craziness!

Cable-actuated disc brakes are great, as are hydros, for bikes. Mechanicals are easy to work on, hydros can be more powerful, both stop better than cantilevered rim brakes.

the pedals fell off my bike last night, so i might not have a choice.
