This is a great, inexpensive crimping tool that makes it easy to make high quality, lasting JST-SM connectors. The JST-SM connectors are very common on Grin Tech products, as well as many other e-bike companies and OEMs. They are useful if you need to replace a broken or corroded connector in a jiffy, or while touring. If so, you can buy the crimper and the connectors together to make things less complicated.
We sell this in part to support the LEVA e-bike technician certification course and training manual. Access to the right tools to make quick repairs is key for better understanding and adoption of this awesome e-bike technology!
