Nominally, 90 rpm is the assist limit. The TSDZ2 can be programmed for higher cadences though. The speed at which it tapers is dependent on what gear you are in. The programmed limit is 28 mph.

There is a group of enthusiasts who have developed open source firmware for the TSDZ2. Installing this firmware is said to allow expanded control of the operating parameters for better performance. I have not availed myself of this resource but it sounds intriguing. I purchased the kit from EcoCycles in Nashville, TN. This vendor does offer the open source firmware pre-installed as well as a lot of support for doing it yourself.
