Finding my (electric) wheels

Hello I've been reading a lot about conversion kits for the last month and last week I was about to order a 500w front wheel hub motor but I stumbled upon these forums and found out that the hub motors aren't too great on hills which is the main reason I wanted the conversion.

I go metal detecting every week and use my mountain bike to get to my permission and it's up hill from my house for about 4 miles and I'm getting tired before I even start detecting . I have a budget of 500 pounds , if anyone could point me in the right direction I would really appreciate it

Thanks !

The problem with reading stuff on the internet is that it's easy to get the wrong impression because you don't understand the context of what's being written.

It's true that most of the cheap 500W direct drive motor kits that you see on EBay are not good climbers, but a 500W MAC at 52V and 30A will blitz a BBSHD in any hill-climb race. It's an absolute fallacy that hub-motors can't climb. You just have to choose one appropriate to your needs. On one project, I used a Q85 hub-motor, which is one of the smallest you can get. At only 36v and 15A, it didn't have any trouble pulling a 100kg rider up a 14% hill without pedalling. It was in a 16" wheel, which more or less doubles the torque.

I think a "cheat sheet" listing different motor types, power, voltage and wheel size would be a great ressource. You are comparing torque with a 700C wheel?

There are too many variables. It's much easier to ask people what they want to achieve or let them tell us, and then give them options on how to achieve it.
