However, EAZY bike is a very new company and cannot be installed on all types of bikes. Swytch is also a new company. Swytch advertises that their conversion kit can be mounted on ANY bike. However, Swytch has a long lead time to ship the product.

Dillenger is a more established company that can ship faster. However, Dillenger’s conversion kits are more complicated and more expensive.
