Hey all. I am buying a new Giant Roam 2 and am planning to convert that bike in the near future. I'm thinking a BBS02 with 500C but then I get stuck for options and ideas. What size chain ring, battery pack, etc...
I started by looking at the kits and I see many out of stock. Maybe I need more education on what I am picking. I have skills, just need help getting started. Thanks.
The Giant Roam is a great candidate for an ebike conversion. You are on the right track picking a BBS02 motor kit with a 500c display. For the chainring size, a 46t is a good compromise between speed and hill-climbing. Lots of choices for batteries, but most of the conversions I do use a 48v 13ah battery. Pick a battery with the 4 slot mounting bracket for the easiest install.
Happy to help with other questions.
