Hi, i would love to get any help with a project i'm working on.
I'm building Electric Rollerblades. Each Rollerblade would have two wheels - one at the front of the shoe, and one at the back (with the motor attached to it). I Was wondering what would be the best proportion between the wheels size and the shoe length? Is it depended on the weight of the person using? The type of the motor? Or maybe the speed?
Any ideas would be great!
thank you!
The basic answer is yes.
I ski and rollerblade and there is a lot that you need to consider. Using two wheels the first thing you need to answer is what type of terrain you are going to be going over, which is what will really dictate wheel size, span and axle to span offset height. Remember that even in a city the ground isn't going to be level which is why regular inline skates the wheels extend slightly in front and behind the foot as opposed to old roller skates that all the wheels were under the foot.
The wheel and motor size are going to be very inter-related since the wheel is calculated like a gear: Big wheels need more torque, small wheels need more motor speed to get to the ground speed goal.
