I really appreciate my Swytch kit. It was so easy to setup and it has been a joy to ride again. In the area I live now it has many hills. So with the Swytch system I am able to ride up them with a lot less effort. I do not have to be a professional cyclist. The design and construction of the components are of very good quality. I recommend for anyone that wants to keep their favorite bike. I have a great bike so now it just makes it even better. For anyone considering to purchase a kit please understand you will not regret it. Thank you Swytch for a great product.
