TSDZ8 750W Mid-Drive Ebike Conversion Kit with Optional Battery - Upgrade Your Ride with Powerful Electric Bike Kit (68mm/73mm BB Length, Universal Fit)

Easy to put onto my Northrock XC6, seller was very helpful when I messed up and needed a different part (the battery did not fit into my frame). The motor itself feels really nice to use; the first e-bike I had was a cadence sensor and WOW the torque sensor is so much nicer. And it's quiet -- I almost didn't believe it was on.

I was pleased that to be able to install this on a recumbent bike for an older person. I would give it five stars were it not for the absolutely horrible and outdated instructions - the product delivered does not quite match the one pictured in the instructions or in the videos I found on YouTube, but it was easy enough to figure out the cabling based on connector types and colors. The speed sensor cable is also too short for a recumbent, but everything works ok without it. The ride is smooth and feels solid.Since the battery is designed to be mounted where a water bottle cage goes, I used wire ties to attach it to the frame and also threaded them through the hole in the front of the battery slip to keep it in place. I considered drilling and tapping holes for it, but want to test it out before making a permanent change to the bike frame. Also, it’s IMPORTANT that the motor rest against the frame on its forward edge when you install it, or it will rotate there at some point after you put it in. There is no “fixing block” in the package or any means of attaching one as indicated in the instructions.

Upgraded old bottom bracket on a homemade recumbent trike. Motor was easy to install and setup after I found appropriate adapters for bottom bracket. Used trike 3 times on 12-14 mile trips and motor is excellent.After using for a few weeks I had a few questions. I contacted Powallon and got overnight responses to the inquiries. Very satisfied with the support from the seller. The assist from the motor is seamless and hardly feels like you are being assisted. I easily can cover greater distances and receive a quality workout.

Seem good.Seller was very helpful and communication was good

Everything in the pictures was in the box. Fit and finish are up to par. I watched my mechanic install, no he encountered no weirdness or missing parts. Installing today I verified the motor and display works. Because I am installing on a recumbent, I need to order extensions for the speed sensor and one brake sensor cable. I will edit this later on this week after full install and test driving. But so far, so good and I am a happy customer.

Excellent product and fair price. Fast shipping

Received, installed, charged battery will not power up. Cannot find customer support contact.Update, working with customer service to troubleshoot.Final update, Worked through testing with technician, found a battery fuse was blown. Replaced and things seem fine.The motor is quiet annd strong. The torque sensor seems very good. Will ride more when assembly is cleaned up but this seems to be a very nice kitLeft at 4 stars because it did not come in working, but they resolved the issues.

This has turned my favorite mountain bike into an e-bike that can compete with the best e-bikes on the market. Highly recommended for the do-it-yourselfers out there.
