I'm doing a project in my a level product design and want to know how i would test my new modification on my pedal. The mod is on the front of the pedal, giving it extra suppourt? New pedal, eh?
Here are some things to think about as you are going along. For the moment we will ignore weight penalties and costs:
1) Does the design incorporate the use of a lock-in cleat, or is it a typical platform type seen on less expensive bikes? If it is the platform style keep in mind that weight on the front of the pedal will cause it to flop down, making it difficult for idiot proof use. This also requires front-back identification as you are starting to pedal;
2) The ball of the foot should always remain over the pedal axle. There is little need for support of the toes (unless you have come up with a novel idea!) and having the extra area may induce the rider to have it forward of the axle reducing pedalling efficiency.
3) There is also the matter of a thing called "toe clip overlap". This is when the toe contacts the front wheel as you turn. Very dangerous.
If you'd like common testing procedures search for CEN test bicycle or EN test bicycle .
Good luck! i think you need to mock-up or modify a few pairs and let some experienced cyclists ride them and give you some feedback...after you're satisfied that they are safe. because cycling shoes (or street shoes for that matter) vary in shape and size, try and get some different types of feet on your pedals as well. |
