• I am wanting to know how much this custom MTB is worth, here is the link: http://www.gumtree.com/p/for-sale/cumstom-built-trek-jack-jump-bike/102382758 www.gumtree.com/p/for-sale/cumstom-bui… Here is the descripton: custom built trek jack has single speed dmr set up giant mph disk brakes front and back front folks xcr lock out folks halo jump tyres just had fsa head stock barings fsa bottom bracket gap pedal arms lock on grips cona handle bars and head stem Do you think this bike is a decent bike? I am wanting to ask another quick question, I am wanting a bike for SPEED, not road bikes as I am 15 and wouldn't look 'cool' me riding one of them. What bike is normally faster, can pick up more speed.. BMX, MTB or a trek. Do you think that customized trek above is fast. Best answer will get 10 points! :)

• Answer:

  Not that.... it's a single speed dirt jump bikes. Dirt jump bikes are for jumps and are smaller so harder work for speed. I can't see the link so not sure on tyre size etc. Trek is a brand who make road bikes, full sus, downhill bikes etc etc. Where will you be riding your bike? If it is just for small distances then a bmx cruiser (larger than a normal bmx) or a dirt jump bike is okay but a dirt jump would be a waste of money if you're not going to use it as a dirt jump bike. Also, cheaper dirt bikes and cruisers tend to be very heavy and not made of aluminium which is what you'd want for lightness. A BMX is fine for short distances too but with bmx, the speed is up to how hard you pedal! If it's for longer distances then look at hybrids, you can get these with rigid forks or light front suspension forks, remember suspension adds weight so will bring your speed down ;) Whatever you do, don't buy a cheap full suspension bike as they are heavy and slow, they're a waste of money.
