Re: Gas tank alternatives
This is my $.02 worth on a rear mounted gas tank for mountain bikes:
Go to the grocery store buy a small aluminum Heinkins beer keg, invite all my motorized bicycle friends for a party, drink the beer, mount the small kit supplied peanut tank inside the keg, and ride off. This way you can have looks, and would not have to mount, (weld), a filler cap and the gas shutoff valve. The tank could be fastened inside the keg using JB weld.
