Sunny Evolution Pro II vs Schwinn IC4 differences

Magnetic Resistance Measures

With the SF-B1805 you don’t have these measurements of magnetic resistance. You can use feel and the number of turns to estimate the level you have set it to (there are around 8 turns from easiest to hardest setting).

Both bikes have magnetic resistance. They are similar in terms of hardness and smoothness. The Schwinn IC4 advantage here is that you can see the level it is set on the console with it having 100 levels to use while exercising.

Flywheel Weight

The SF-B1805 has a heavier a flywheel at 44 lbs vs 40 lbs for the IC4. The extra flywheel weight should result in a more fluid motion in particular at the top range of the resistance with the momentum of the wheel helping to pull the pedals through the full pedaling cycle.


The SF-B1805 leaves you to your own devices but you can add sensors or a monitor to get the measures you want except for resistance levels and Power. You can add cadence, speed, distance and time and heart rate.

Only the IC4 comes with a console. It has most of the measures you want – heart rate, RPM, resistance level as well as time and distance. It doesn’t measure power (output) but you can get a calculated number with Zwift and other third party Apps.


The IC4 has a more racing style seat with the SF-B1805 has a more padded and wider seat. Customer feedback is that the Sunny seat is much kinder to more people’s sit bones. With both exercise bikes you can change the seat easily.

PedalsThe IC4’s dual pedals allow you to use SPD spinning shoes or athletic shoes to cater for people’s different requirements within a household.

You don’t have that choice with the SF-B1805 with the included toe cages fitting athletic shoes only. However, they can be replaced.

Max User Weight The Schwinn IC4 is rated to cater for people up to 330 lbs and the Sunny SF- B1805 has a lower capacity rating of up to 300 lbs.

Bike BuildThese are both solid bikes. The SF-B1805 is the heavier bike at 125.7 lbs vs 106 lbs in a more compact design. Both provide a good stable platform for indoor cycling workouts.

Q-Factor This is the measure between the pedal when measured horizontally – it is measure of alignment with the shorter the number the more aligned hips, legs and ankles are, which helps reduce stress on the joints. The Sunny SF-B1805 has the narrower one coming in at a respectable 182 mm.

Customer Height The Schwinn IC4 has a much wider range of height accommodation from customer being between 4ft 6 ins and 6 ft 6ins with the SF-B1805 being best suited for those between 5ft 2 ins and 6 ft 2 ins.

Extras The Schwinn IC4 is out in front here. The Sunny SF-B1805 has the tablet mount and water bottle holder. The IC4 has those plus the dumbbells an holder, dual pedals, USB charger port, heart rate strap, Bluetooth and an App.
