Is it possible to add front disc brake (possibly a rear disc brake) to a single speed
Is it possible? I might change the fork and wheel with disc brake screw holes.

You need to give a lot more info. What's the bike, how old, do you have pics? If you have an 1 1/8" head tube a front brake will be easy. Rear isn't usually though trek made an adapter to some of their bikes from the 00s. Most won't have this option but no clue without a lot more info.
|
What bike are talking about? Why do you think that you need a disc brake, front or back? Single speed bikes almost never have any need for disc brakes. Why do you think that this is needed?
|
Possible? Certainly. Worth the time and expense? Probably not.

As the front does most of the braking, just buy a disc brake fork and run disc in the front. I've seen many a bike with front disc and rear canti.

Can I mainly use the front disc brake and remove the back brake?
If it were a 'fixie' then it is possible to use backpedal force to act as a rear brake, but a single speed with a freewheel should have F & R brakes. |

Keep the rear brake |

You should not do that. Your rear brake is a backup safety feature. If your front brake fails, you need the rear to stop you. If you suffer a flat front tire, using the front brake is extremely dangerous.
Keep the rear brake |

Ok but it is possible to add a rear disc brake to the bike? It possible on the front but the back?
Don't forget as well that your wheels are probably not disc compatible |

No way to know without a proper description of the bike. The phrase "normal single speed bike" means nothing

It's possible on the front but you will likely have to get a new fork. Depending on the bike it may be easy or very difficult to find a fork that fits.
It is possible on the rear, but only if you are willing to get disc brake mounts welded or brazed onto your frame. These possibilities are based on the assumption that you don't already have disc brake mounts. Generally speaking, caliper brakes that come stock on most road-oriented bikes are more than strong enough on the rear - you can lock up the rear wheel to skid, and no braking power beyond that is useful. I believe a good disc brake on the front adds a bit of stopping power and control, but most people using modern dual-pivot caliper brakes find them sufficient on the front as well. If your bike was older or very inexpensive, you may have the older style single-pivot caliper brakes, or the ancient style centre-pull caliper brakes.. Upgrading to decent dual pivots would give you much better braking and would be a bolt-on upgrade requiring no modifications. |

F disc & rear V brake is a good solution. If there are no disc mounts on your fork then you need a new fork.
V brakes are generally acceptable stopping for most uses - when they were introduced in the mid '90s it turned the bike world on its ear. Discs are marginally better, especially in wet conditions, but properly set up V brakes are strong enough for just about any situation I can think of. |

Just three more posts until you can post pictures, Adis ! Keep 'em coming!
What colour is your bike? |

You’ll also need the tools changing the fork. An Allen wrench, a hacksaw and guide, something to set the starnut if it’s threadless, a T25 torqx for the rotor bolts (Allens can be used) It’s hard to estimate but around $50 to $100. If you don’t want to do the work yourself, expect about 1.5 to 3 hours at $75 per hour. So the question to ask is your “need” for disc brakes worth the cost? I don’t know what brakes you currently have are but there are good v-brakes and bad ones. Good ones are every bit as good as good discs and bad ones are every bit as bad as bad brakes. Avid Single Digits are good ones. Shimano Deore and higher are good ones. Paul Motolites are excellent ones, but they are expensive...less expensive than doing the conversion you are proposing, however. And much less work to install. |

Yeah - and what kind of chain lube do you use? (separate post)

V brakes get a bad rap mostly because current bikes using them are equipped with bottom of the barrel quality callipers and brake levers. Good v brakes work extremely well, far better in fact than cheap cable operated disc brakes. before embarking on a very expensive upgrade to a single front disc brake, look into a very simple upgrade of the brakes you currently have

Plus the V-brake calipers are completely out of the way of my panniers. Cheers |

It would require a huge amount of work to add rear disk brakes to a bike that wasn't built for them. It would require even more work with a single-speed. Consider this: with most single speeds, you adjust the chain tension by moving the wheel back and forth in the dropout. If you had a disk caliper mounted to the frame, the disk would move relative to the caliper, and that would be Bad. There are single-speed disk-brake bikes, but these have special dropouts where the whole dropout moves to tension the chain, and the disk caliper is bolted to the dropout. Adapting a frame to do this would almost certainly cost more than the frame is worth.

It a blue + orange+ white. Also I'm 15 years old. I ride this bike to school everyday, so yeah.

In the meantime, give brand, model, and wheel size.

One of my friends found a widget to put a disc brake caliper on a bike without the mounts @ Walmart...
reduce quality expectations as you should given that source.. |
How is school? Back to in person or just online? FWIW the idea doesn't make any more sense now than it did in March.:thumb:
