Hello everyone,
I would like to start my first ebike project. I read some articles and watched some videos to get a better feel for the project. Since I attempt a technical college, with it's main emphases lying in electrical engineering, I have a basic understanding of electrical circuits. Nonetheless I'm not that familiar with bicycles and have even less of a clue about the wide range of products on the DIY ebike market. So I hope some of You give me a bit of advice.
I thought about a 52 V (14pXs) System using this bike:

I choose it because I like this type of frame (with upright seating position), it's large (I'm 6"4) and it seems durable, with it's double tube construction. The bike is 20,5 Kg (45 lbs) with me, it will be 95 Kg(210 lbs). It has a hub dynamo, in the front wheel, which I hope is not a problem. The drum brake and hub gears though likely have to be removed.
My budget is flexible but I would like to keep it under 1000€, excluding the bike.
As You can imagine, I won't go running down mountains or participate in races. The bike should be able to hold a constant speed of about 32 kph (20 mph), although some faster bursts would be nice if I'm in a hurry. As I'm comfortable with pedalling to get it going I'd rather have more top speed then acceleration. The region I'm living in is mostly flat.
Since 1000W hub motors already integrated in 28 inch wheels, seem hard to find in Europe, I guess I have to buy the motor and pay a bike shop, to get it into the wheel.
I don't really know about the controller. I don't need a lot of features, perhaps cruise control but that's not a must have.
It would be great if the battery had high energy density because the weight of the bike is already high and I don't want to pack a huge box on to it. If it's much cheaper I think I'm able to build a battery myself but then the question arises how I get hold of a battery box; one that would be lockable desirably.
As the build should be reliable and long-lasting (for as a student you don't always have money), I'll presumably get one of those Luna chargers to charge to 80% or some kind of other charger that is more easy to get in Europe.
Thanks for your attention
Felix
