Vado 5.0, hands down. If you want something light you can't beat the Vado SL.
After reading the Vado Club forum I am still interested in purchasing a Vado Turbo 5.0. Found all of the comments very helpful and informative. I have owned ebikes for more than nine years starting with kits to convert first with hub motors and then graduating to mid drives. I do own an I zip peak which required a motor replacement shortly after it was purchased, that was six years ago and it has not been to the dealer since. I am mechanical, do my own service and have made many upgrades to this ebike. That said I feel that if I purchase the Vado I will need dealer service because the bikes electronics are much more complex and you can't do your own firmware updates. I live in the Los Angeles - San Fernando Valley section of California and would appreciate a referral to a reliable LBS for sales and service.
