Both the Sunny SF-B901B and SF-B901 indoor bikes are solidly built and can be ridden sitting or standing to mimic riding on different terrains such as flats and hills. Both spin bikes feature front and rear stabilizers and adjustable levelling feet for stability. Both bikes offer a maximum user weight capacity of 275 lbs.
The Sunny Health & Fitness SF-B901B and SF-B901 are suitable for both beginners and more advanced cyclists, and are easily adjustable for a custom fit for different rider heights. The saddle on both of these spin bikes is 4-way adjustable, i.e. up/down and fore/aft, while the racing-style handlebars offer multiple hand positions and are adjustable up/down.
The only other difference between these 2 spin bikes is that the Sunny SF-B901B comes with a side-mounted water bottle holder which the SF-B901 does not have.
