Skyblade

The bike weighs 15kg at moment, so I guess I got around 8kg to play with, I'm guessing that the batteries are the heaviest then the motor? But as long as I stay around that mark I should be golden. I understand that guys here are road enthusiasts, is there a forum that's suited better to my requirements? Although I can't fault the information I've had so far here and I thank you all for it.

Ok so been doing some research on hub drive motors and mid drive motors and I've come to the conclusion that mid drive is going to be the way I need to go regardless of the fact that I probably won't convert it back to a normal bike after its built. One thing I want to ask is that do mid mount motors have a free wheel option? I.e if no battery is on the bike can I still pedel with ease or will I be pedeling against the motor?

So would it be better for a geared hub, is the other type a direct drive? What's the advantages and disadvantages of each if that's a thing?

Its part public and part private as it passes through farm land (we already have permission to venture on this land as my friend owns part of it). The parts that are public we obviously are very courteous to the people using it ( usually other bikers).

I'm 100kg at moment, I'd prefer top speed over climbing as I have very low gear ratios at present (probably a little to low), the track I run on has a few hills that are fairly steep but there only short there is a run that's around 1.9 miles of straight gravel stretch with a slight incline, it's this part I want the bike to go up at a fast speed as it's a little boring on that part. Most of the other parts the motor will just probably help to keep it going or am I looking at this wrong?.

I'm prepared to pay as much as needed, if I need to make my own battery then that's what I will do. I need to start somewhere so if I need to make it work I will. There is a rear frame that sits on the back swing arm, I just need to make sure it will clear th seat when the suspension is fully depressed but this is not ideal. I think making my own batteries would be the way to go. The rear forks on this bike is I think 141x9mm Boost Open QR, I think this is going to be my main issue, what size is the biggest motor I could fit in this space?

I'm basically after the most possible power and speed I can get away with on this particular bike

I would like to have a bit more top speed than 15 mph as I can pedal faster than that already, the battery I don't have a issue if I can't fit within the triangle I could put on main cross bar or if it really came to it I'd get a rear mount over the back wheel. There are multiple places I could fit it unless I'm missing something here? Are they bigger than a car battery?

I don't want a motorcycle looking bike, I need a hub motor as I 2ant to be able to put the bike back to stock with ease just leaving wires in place and just removing the rear wheel, controller and battery. The hub motor needs to be powerful enough to power me up some pretty steep hills consistently using the bike I have even if it means getting a reduced rear sprocket or something. Is it possible that I could use a lower power motor to achieve what I require?

Hi, I'm very new to this scene and I'm not sure if what I'm looking for in a ebike is within line with most of you here. I currently have no ebike but I'm interested in making my own conversion to a ebike. I have a voodoo canzo MTB (not a great or expensive bike I know) this is what I want to convert to a ebike. It will never be used on the road (ever!) It will be a pure hill/ cross country bike, some of the hills I climb are very steep and looking to take advantage of the ebike to help get up these (usually end up getting off and walking). I'm hoping to come here and get some advice on building my own ebike and what I need to get (what components are best for my needs). I'm totally new to this and any help would be much appreciated. Looking to build something a bit more than average on the power side. I was to thinking somewhere in the region of 3000w - 5000w motor (providing it will fit within my rear dropout) with 72v battery and a decent controller to go with it. Any advice would be superb, thanks
