i need a vehicle that will carry some groceries up hills and through the snow. so thats why im building this trike. the thing that will be great about it is the full suspension. im using a 54 tooth sprocket to gain torque, no need for speed on ice..or lugging a basket full of cargo up steep hills. it will have a single axle rear end with backstop brakes on the rear and v brakes on the front, a flat rear tank that mounts to the rear post. and a turn signal/ brakelight/ horn kit. im using an old antique steel milkcrate for the groceries, and whatever i cant fit in that will go in my backpack. im keeping the front derailer intact to shift through the front gears only while pedaling ill have to modify a rear derailer as a tensioner the trike axle i got from my buddy had a backstop brake that was modified with another sprocket the same size on the opposite side and then drove the left wheel only and had a seperate axle floating on the right. my idea is to use a single axle which i purchased already, and use the two sprocket combo to drive both the pedals and the motor. the case needs modified though to fit the big 54 tooth sprocket. the mounting of the wheels has got me pretty much stumped though, i need to fit the hubs on a 5/8 inch axle somehow. then to top this thing off ill fab some studded snow tires and let em rip. im hoping the 26 inch tire 54 tooth sprocket combo will get me enough torque, if not ill think about smaller wheels maybe 24 inch.
