Sorry but it isn't possible to reset the accounts. Only way for you is to make an alternate acc (you can make 2 per e-mail)

It really doesn't matter. If you want to play like a new game you just don't have to trade till you pass the E4. Some people want to trade before and some don't.
You get the bike by giving the voucher in cerulean. Beforehand you obtain the voucher by paying the rent of a npc in Vermillion city.

This is also partially a player's fault. You could have easily evolved it at lvl 99 and used later a rare candy to lvl to 100. It is never safe to evolve a poke at the last level.
You're suggestion is noted and we'll discuss it tho.
