Bike Ark Jaz- Hybrid 21 speed is a great city/hybrid bike for fitness rides and city commute. The bike is compact, lightweight and comfortable to ride. The build quality of the bike is admirable, the seat is comfortable and the high tensile frame is light in weight which gives it an edge in its category. Handle grips are soft, comfortable and feel good while riding. The frame design and metallic grey paint job are aesthetically pleasing. Shimano shifters and derailleurs are efficient in working but sometimes face derailment during upshift in the front derailleur. The power calliper brakes are not up to the mark which gives it an average braking performance. However, breaking is fine at moderate speeds. The build of the bike is more towards city bike side rather than a hybrid. Full mudguards cannot be installed due to confined space between the tyre and the fork, while 2-piece mudguards can be installed. 700 C Kenda tyres have tubes with Presta Valve which is uncommon for the Indian market resulting in my buying an adapter for common bike pumps. Overall, the bike is a great buy for daily commuters and hobby riders at this price range.
