What kind of pedals are the wheelchair good? Aluminum alloy or plastic?
In fact, the pedal itself does not allow the user to stand on the top, so easy to cause the wheelchair overturned, so the normal use, the pedal is made of engineering plastics can be used, the normal use of 3-5 years is not a problem.
But the price of aluminum alloy pedals is very expensive, and the cost of engineering plastic pedals is only 1/10 of that of aluminum alloy pedals, so most of the wheelchairs now use engineering plastics to produce pedals
Of course, the aluminum alloy is better, stronger and longer service life.
