When the bikes arrive, they must be assembled, which can be done more-or-less easily, just be sure to follow the instructions in the manual.

Both units feature 49 pounds heavy flywheel, ensuring smooth ride, regardless of the spinning speed or resistance level.

Also, transport wheels help the user move the bikes around when required. Bikes are robust and feature strong frame - if there are squeaks of any kind, check if bolts and nuts are firmly on their position.

Personally, exercise bikes like these should be placed on permanent position and used as often as possible - cardio exercises don't have to be tough to be effective, since bikes like these may be used in living room while watching TV.

Regardless if you place your exercise bike on the permanent position or not, it is good practice to place it on the durable exercise mat in order to protect the floor and even more dampen exercise noises.

Resistance is adjustable using leather pad and convenient and easy to use tension knob. Also, there is a flywheel break which may be needed to stop the flywheel in emergencies.

Since there is no resistance measurement system of any kind, SF-1002 and SF-1002C exercise bikes feature no electronic console of any kind, leading to very simple to use and maintain units.

However, if required, there are many ways to monitor user exercise and collect exercise data - for example, one can use chest strap with Bluetooth connectivity to monitor heart rate during the exercise, while other exercise gadgets may be used for collecting other data.

Personally, when I use bikes like these, stopwatch is more than enough...


 To help one stay hydrated during exercises, bikes come with the water bottle holder on the right side of the unit - bottle is easily reachable, although relatively low.

Foot pedals are of caged design - they help with the proper foot placement and keep the foot firmly during exercise.

Maximum user weight is 275 pounds (~125 kg) which is good, although it could be better, since 300 and 350 pounds models are getting more and more common.

Seat and handlebars are adjustable, helping the user to have comfortable ride. Distance between seat and handlebar can be adjusted between 18 and 23 inches, while user leg inseam is between 29 and 41 inches.

Q-factor of these bikes differ slightly, and for SF-1002 (Belt Drive) it is 184 mm and for SF-1002C (Chain Drive) it is 190 mm - this 6 mm (~0.24 inches) difference is rather small, but it is worth mentioning.

Both SF-1002 and SF-1002C feature the same warranty: 3 years structural frame, 180 days other parts and components. Warranty perhaps could be better, but with practically no electronics, there isn't much to go bad on these bikes anyway - just be sure to assemble them properly and to periodically tighten (if necessary) bolts, nuts and other parts.

Note: exact maintenance procedures are listed in the manual. Before the very first use and especially before the assembly, be sure to read the manual thoroughly.

sf b1002Long Story Short: Sunny Health & Fitness SF-1002 and SF-1002C are affordable and reliable home exercise bikes that will help you burn tons of calories and increase your strength and stamina.

Although their ride resembles the ride of the road bikes, one can't expect exact simulation of the road ride - much more expensive exercise bikes come with road simulations based on the Google Maps.

If you are looking for simple, mechanical exercise bikes, consider one of these.
