Adding electric assist to a bicycle

No I don't want gas powered so just forget that advice( I know the first reply is going to say why not gas or something like that)

Anyone have experience with this?
I've seen kits and they vary from $250ish that don't come with a battery, to $700 for everything including a battery. The kits replace the front wheel too. Does the motor have it's own braking system? My bike has disc brakes right now. I'm not looking to convert to electric completely, I still want it to work with the pedals. I have 26" wheels

What's the point in a bike if you put an electric motor on it?

There's a guy in reno that did it, and posted a thread on an r/c forum I'm on.

here you go: How to Convert Your Bicycle to an Electric Bike Using RC Car Batteries! - Forum of last resort - General RC topics that don't fit in ANY other area @ URC Forums

fwiw, I've looked into it myself and it seems like you could buy the components individually and build it cheaper. the control units were pretty cheap on amazon.

I had an OLD bike with one of these on the front fork. Basically, it used a lever to push a motor driven wheel down onto the tire and the motor turned the wheel for you. It was fun considering the age, and the fact it had a car battery. I imagine with a better battery you could get a longer run time

Just a mountain/hybrid(that's what I think they call them now) front shocks, 26" wheels and 21 speed.

That's what I was looking for. Looks like he added a battery to a basic kit on the cheap. Defiantly better than the highest price/all inclusive on kits I've found

ive thought about the ones that are built into the hub

ive got asthma, I can ride on flat ground ok, but I need a boost to get up the hills.

only place I can ride around Atlanta is on the trails made from old RR tracks so they dont have much hill.

I've been browsing Craigslist for a couple months and scored 2 electric bikes today. They have 5 levels of electric pedal assist and a twist grip throttle controlled front wheel hub motor. Now if only there wasn't ice everywhere. They were pretty sweet on the test rides. They have 7 speed internal geared rear hubs and a front disc brake too, and they don't weigh much more than my early 60s Vintage Schwinn. I've seen a few good deals on kits too but they are hard to score when you live several hours away like I do from the Denver Metro area and any other larger cities but it paid off today. 6 hour roundtrip drive for the win, and they each cost less than just 1 new battery would.

You should be able to find a 26" motor hub wheel with a disc brake setup. In either a front (easier) or rear wheel config. You just have to make sure that the hub supports the rear gear cassette you have.

You could always run a front and rear electric for two wheel drive.

The hub motors don't have any type of internal braking that I know of. You still rely on either a rim brake or a disk brake.

I picked up a cheap electric scooter for the kids and found this place for parts. They have kits to convert your bike.

Direct drive hub motor can regen, but regen doesn't replace good brakes, it's more of a brake assist or range extender. Cheap kits tend to have problems, like everywhere get what u pay for or have to find deals/do self, particularly batts and electronics. General advice keep to lower power if using front wheel hub motor. Looking to do the same thing soon, just started researching. Endless sphere wiki is a good place to start. Good luck, keep us posted.

I have a fat tire ebike. Cheap hub motor and controller. $399 or so I think? I do have a 20ah 48v lipo battery from ping battery on eBay. Front hub motors are good but remember you need steel front forks as aluminum will fracture from the stresses. E bikes are very fun.

Will have to look and see what forks I have. I was a little confused how the front brake comes back into play with a new front wheel since I have disc brakes instead of rim brakes. This may not happen now. Was going to use it to get to/from bus stops but they stop running before my class would get out at 10pm

rear wheel is better. there is a bosh kit that has pedal assist modes from mild to scary.. fits your cassett and disk rotor. 600 bucks. but you gotta get spokes cut and relace.. easy or another 50-100 depending on your shop.. will get you a kit # when i get back home

I read on the post Makya posted that he used a torque bar/bracket thing. Will that allow or help with aluminum forks? I can make any bracket if needed. I definitely need to do this. Im WAY out of shape.

I have been looking at this for awhile. Hub motors are okay but I was looking at the bafeng 1,000 watt setup. More expensive but I hear really great things about it.

Hebb ebike is pretty cool. Pedaled up a steep hill like lance Armstrong on drugs today, minus spandex and helmet. Street tires were better on snow than I expected.

I'm planning to add a mid drive to my fat tire bike too since I have an extra battery to play with now and I got a used 600 watt Schwinn Scooter made by Currie to pull the motor and chain drive from.

What wattage should I look for? I'm 155# and live in a VERY hilly area. Would have to go up a hill to get home no matter which direction I come from
