After putting together my first ebike and riding it for a couple of months, I learned a hell of a lot. The shortcomings of adding a high power ebike kit to an old hardtail MTB became very obvious very quickly.
Using the knowledge gleaned, I'm about to start building what will hopefully become my general purpose bike, which I will use to commute a few days a week and also have 'a bit of fun' at the weekend.
My first setup is Crystalyte HS3540 with a 40A 36-48V controller and APM display.
Power has been LiPo 10S and 12S charged with an iCharger 1010b+
10S gets me 25mph top speed on the flat, 12S gets me 30mph.
10S is fine for blipping around in the lanes where I live, however, in traffic 12S is much better being able to get off the line quicker. Also 12S seems to be great for hill climbing with this motor, I've been able to climb the steepest longest hills on my island easily at 12S.
I've been riding motorbikes for nearly 25 years and so I'm used to riding at speed on the road. The maximum speed on my island is only 35mph though, which makes it ideal for an ebike imo.
I want to go full suss. Riding a hardtail on our roads at 30mph plus isn't pleasant, I find myself standing on the pedals and off my seat.
I want plenty of stopping power. My current 5 year old brake pads and knobbly tires are terrible and dangerous at 30mph.
I want to have the ability to hit 35mph when needed, we have a few straights and coast roads where it would be safe to do this.
I want the ability to do 24 miles range with a couple of big hills, this is a lap of my island.
Proposed Kit List:

Crystalyte 40A 65-89V : Got
20S Lipo : Got
Maxxis Hookwork 26" 2.5 : Got
Velocity Psycho Rim : Yet to Order
Avid bb7 Mechanical Disc Brake 203mm Rotors : Got
Mountain Cycle Fury FS Frame : Got
Marozochhi Bomber 888 Forks : Yet to Order
Here's a pic of this frame built up:
I'm going to have to fabricate a battery & controller mount for this frame, I'm thinking something similar to Jimbo's big hit setup will suit. I'm hoping I can use that gap between the top and bottom bar to mount the contoller in some way. I'll also probably need to fab some torque arms too, not sure which way I'll be doing this until I have it in my grubby mits.
There's no getting away from it, the one I bought is, well, green !
I got it cheap though, so I might have to strip it and get it painted black.
That's all for now, I'll try to add as many pics as possible as I go along.
Any input gratefully received.
