Would have stayed clear of grubee garbage, Also, I spent over $700 on my first commuter bike. It was a tricked out cranny with a 66cc grubee. It looked cool ( actualy, I still have it and rode it to work today) but after spending so much money trying to make that bike fast and reliable, I then realised that im fine cruising at 25 to 30 mph and I later got a R/S eho35 on a friction drive kit from dax, and there is no going back. Sure, I build all kinds of bikes for others, some selling for more then $1500, but when im going out to ride? I take the simple eho35 bike. The point to this story?
Before you spend any money on a setup, please take the time to think about what you want it for and dont fool yourself into thinking that you will be able to rely on a cheap bike with a cheap china girl for day in day out transportation.
