Hi all. As the title suggests I am looking into producing Aluminium E Bike mountain bike frames. For the time being, I am looking at the idea of converting a standard production frame as I have just done for myself with the 2009 Norco Empire 5 slopestyle bike below \|/
Gussets still need to be added to this frame yet, just before it goes in for powdercoating. The RH drivetrain cover needs to be finished also.
It is up and running with a build thread in the Non Hub Motor section - Norco Empire 8150 Build + 1st Video.
These are my aims:
Produce both a hardtail and full suspension versions.
Versatility - one frame can be used for hub-motor, Cyclone and hopefully Recumpence's RC Reduction unit with rear plates to suit each application sold individually.
- frames to be modular up front to allow users to add extra frame width should they wish to add more battery capacity later on.
The hardtail below is a Brand X Dirt Jumper III which i am keen to use. I own one (pictured) and think it'd make a great hardtail choice - light, strong, disc/v brake bosses, 1-1/8 headtube 120mm long, gussets and approx 68 deg head angle with a 120mm fork to suit our higher than pedaling only average speeds. Why a jump bike? Strong dropouts and built to take a pounding and come out smiling. The largest they make are 15" but with a 550mm c-c top tube length, are bigger than the number suggests plus i can extend the top tube length further if needed. Frames will only be one size to keep it simple, probably medium.
I am about 5"9 and comfortable with a 50mm DH stem.
I will post up a sketch later of the design i have in mind but am also looking for suggestions from you guys for other ideas you've got and suggestions for reasonably priced full suspension frames to be used as well. Frames must be either 6061 or 7000 series alloy and of a design that the rear suspension will clear the insert like the Norco above. Also would ya's want a DH based frame or more XC orientated to use shorter forks/better pedaling. This is your opportunity for input so have your say!

These would would be great but have no v-brake bosses...
Cheers!
