This is a 24volt electric bike speed controller. That is kinda sold as is because I haven’t used it prior to now three months. The last time I used it was once working perfectly. I just wanted to point that out because it hasn’t been used in a even as. But I am pretty sure it is going to work because it has been in a protected place since then. If you have an interest than you’ll message me and I can be happy to reply and answer any questions ?
