Guys i need help

[Chamath]

So i am new to this whole motorized bike thing. i just have a problem with braking. so it takes like 30 s to brake this is dangerous because once i ran a red light because of this and stopped in the middle of the road and slightly hit a pick up truck ,luckily nothing happened . i just need to know how do you brake properly

More details. What type of brakes do you have? I'm still in process of building my bike but went with front and rear 203mm disk brakes. Hoping they work as designed.

The bike is Single speed and has one rear brake

ditch it till you install a front disk brake.
it's not worth losing your life over.
also pull in the clutch when you brake so your brakes aren't also fighting the engine.

how much does it cost to install front disk brakess

 

[Deleted member 12676]

find the parts online to do it yourself

if money is a problem, go to a used bike store & get a front fork that has mounts for a v-brake - in my area, these cost about $15, then $5 or $7 for used brake arms with pads & $5 for used lever & cable

I'd take it to a local bike shop. Your rear hub might just need to be replaced or rebuilt. Make sure you know what they will charge for and that they won't make any assumptions with your money and do extra work. You can do it yourself http://www.parktool.com/blog/repair-help/hub-overhaul-and-adjustment . One of the bolts back there may need to be tightened. Depending on your setup there may be up to 6 bolts on the axle.

Another option is replacing your rear wheel with something like http://www.amazon.com/Avenir-Nutted-Cruiser-Coaster-1-75-Inch/dp/B003RLCE76 or http://www.bikewagon.com/sta-tru-26...6&cadevice=c&gclid=CIr5t8ultMkCFQISfgodngwGlQ . There are many other options out there.

I wouldn't depend on a front brake alone. It is a good idea to install one in the front but as you now know it's always best to have a back-up.

30 seconds is ridonkulously unsafe. I'd stay off the road until you buy a new set of brakes or service the existing one or buy a new wheel but learning how this service is done is invaluable. My bike is set up for disc brakes but for now I am depending on the coaster brake. With 4" rims, rim brakes are a huge challenge so eventually I will order these http://shop.soulcruzers.com/STOMPER-front-hydraulic-disc-brake-kit-stomper-hydraulic.htm or possibly something off of Amazon like http://www.amazon.com/Signswise-Mou...F8&qid=1448754891&sr=1-5&keywords=disc+brakes. Make sure you know what your bike will accept if you do order it online.If you do go with disc brake I would clean them with isopropyl alcohol after every ride for the first 20 miles. Some of them have this manufacturer film on them that keeps them looking good during storage but it impedes braking slightly until it's worn off. Just be an informed buyer.If you have a regular 26" mountain or cruiser style bike cantilever or V brakes will work great as well like Crassius was saying. Invest as much as you can for a quality brake set. Whether it's rim or disc brakes they are designed for a bicycle and not a motorized bike so find quality but don't confuse expensive with quality.

I just wanted to add that the front brakes has the most braking power due to weight transfer when braking. As a stop gap solution, I would just install a pull brake in the front. They are running for ~$15 on eBay.
