Freewheels are more and more rarely found in modern bikes, they are most frequently used in low-quality cheap bikes with 1,5,6,7-
speed gearing system with the smallest 14t (14-tooth) sprocket. Modern high-quality bikes use 8,9,10 and even 11-speed gearing
systems with the smallest 11t sprocket. Smaller number of teeth on the smallest sprocket gives an opportunity to get a higher gear.
The ratchet was moved to the wheel hub and the development of freewheels stopped at that, for a number of reasons cycling industry
chose a hub with a ratchet construction and respectively a cassette without a ratchet.
In recent years, only low-quality Shimano and worse freewheels remained on sale. However, with the advent of motor wheels the
situation changed again. Mounting an additional hub in the motor wheel (ratchet) complicates the design and increases the price
substantially. E-bikers often need pedals only as a footrest, so there is no point in paying for extra blocks and the cheap freewheel fully
pays its way. Therefore, motor wheels are usually manufactured with freewheel mounting seat (35mm thread).
There is also another approach to the electric bike construction - maximum preservation of positive qualities of the donor bike. And
the role of the gearing system is not the least by far. For an expensive bike to become an electric bike and not lose its valuable, high-
quality, multiple-speed gearing system, 7, 8, 9-sprocket freewheels are required. And to comfortably combine pedaling with the electric
motor at a speed higher than 35km/h a small 11t sprocket is necessary.
Our online store can offer you to buy a high-quality 9-speed freewheel with a small 11t sprocket.
Also be aware that the chain, shifters and switches are compatible only with the following options: 5 speeds are suitable to 6, 7 speeds
are suitable to 8, 9 speeds are suitable only to 9 and 10 only to 10. This means that instead of an eight-speed cassette it is quite
possible to use a seven-speed one. The 7-speed cassette is narrower than the 8-speed one, but has the same distance between
the sprockets, respectively, the same switch step. While 8, 9 and 10-speed cassettes have the same width, but the larger number of
sprockets requires a smaller distance between them, a narrower chain and a smaller switch step.
If the speed 30km/h is sufficient for you or pedals mainly serve as a footrest in your electric bike, there is no need to increase the
costs. A regular inexpensive freewheel fully performs its functions.
Number of teeth on the sprockets: 11, 13, 15, 17, 19, 21, 24, 28, 32.
