Well, I have owned the Yo Bike for 3 months now, and think this is a good time to write the first review about this beauty. I bought it against the wishes of most of my friends, but now realize that my decision was very apt given my driving conditions. I use this bike for all my household works and travelling that does not exceed 50(km).
The best part is that I dont need to take care of anything except cleaning and pumping the tyres. The battery is fully charged in 5-6 hours and consumes 3-4 units of power. Speed is not very good, but in city roads driving conditions in Delhi, its acceptable. I travel alone most of the time, and that is what the company recommends; but I have carried my small sis few times and it works pretty well; though not recommended.
I drive it almost thrice a week, and am really satisfied with the performance. Other positives - No DL required, No registration, No Insurance, Just purchase, charge, drive and Enjoy . though I recommend a helmet. Last but not the least, it is an innovative way towards Environmental concern. Chak De India!
