Friend needs a strong crank/crank arms.
So i'v been getting my buddy into riding with me (just in the city and stuff) and he was using his brother's Walmart Schwinn which was doing fine but the part of the crank arm that the pedal connects to got stripped out. So he went on to use his brother's girlfriend's Schwinn (same bike only womens) and the same thing just happened tonight.
So I'm looking for a cheap solution on what to do here, he's a good 220 pounds. So i need somethin that will be strong enough for him.
Whats the cheapest solution to get him up and riding again? The rest of the bike is completely fine, its just the damn crank.
I was thinking of just welding the damn thing right in, but i think the arm is made out of aluminum.
