Hi! You must be age 16 or older to operate a Rad ebike. Check out our new user guide here: support.radpowerbikes.com/Assembly_and_how-tos/New_owner_how-tos/New_owners_guide 😎
Hi! The RadRunner 2 has a 300 lb (136 kg) total payload capacity. The integrated rear rack has 54.4 kg carrying capacity which is included in the 135 kg total so this sounds like this bike would accommodate your needs.
