What I Like about Sunny Health & Fitness SF-B1509

Sunny Health Fitness SF-B1509

Combination Pedals
The best thing about this bike is its Integrated Dual-Action Combination Pedals. They feature SPD clips on one side of the pedal and toe caging on its other side. This bike also allows reverse pedaling.
These pedals are constructed from aluminum alloy and have standard threading on the link points. So, if you want to replace the pedals with any other set of pedals, you can suitably do that.
Heavy-duty Construction
Constructed from a heavy-duty steel frame and durable crank, this spin bike certainly ensures high endurance against long-standing use.
Perimeter-weighted 40 pounds of flywheel provides finest momentum and solidity to this equipment. Although this weight is not very heavy, it is still fairly solid and stable to handle any intense workouts.
Simple design
This bike features Friction Resistance type of system. It is very simple yet effectual for your cycling workouts.
Leather pads are linked with the Tension knob, so when you adjust this knob, resistance level will be changed in micro increments.

What I Didn’t Like about Sunny Health & Fitness SF-B1509

Sunny Health & Fitness SF-B1509 Indoor Cycling Bike does not come with Cycle computer. Hence, you cannot track or monitor your workout routines whatsoever.

There are no Resistance levels marked on the Tension Knob. You have to pedal and check what intensity you are getting with resistance.
Manufacturer’s Warranty is much underprovided. Comparatively, other spin bike models available in the market provide a consistent warranty.

Handlebar only allows 2-way adjustability
