Well I've ridden my bike a dozen times since installing the kit, with the 42T Bling Ring, and am very happy. The chain has not come off once! Let's see if this remains the case all year. If so I will consider this a very good investment.

good

Both items are top quality, communication was good, had to wait a while for back order on controller but it was ship promptly when available, more than happy

Sehr gut danke schön

Very happy with this purchase. Items were delivered quickly and in great condition. Highly recommend this company.

Fitted this kit for my 13 year old grandson. Should have taken a day + but I had some bike issues so I needed to go out and chase down what was required.
This is second one of these and the previous was similar effort/time. Nothing major mainly used bike issues, its just they cant be everything for every bike so a small amount of problem solving is required. End result is 13yr old now thinks he's 15 so a good result, probably not for his mother.

All in all worked out excellent.

What was requested. Arrived quickly. Double thumbs up.

Good service
Very happy with product

Works great

Motor Grease - (Nylon Gears) RED

Excellent product thanks

Great battery, easy fit. Great company to deal with.

Fantastic, the knurled edge grips like shit to a blanket on the bottom bracket. And when using the 1000 watt Bafang on an aluminium frame it needs to.
Great product if you need to get extra space to stop the full suspension rear swingarm from binding on the Polygon 2021 Siskui D6. Already snapped a lower bracket pivot bolt because of this so hopefully this will solve the problem…

Thanks guys. Couldn’t find this part anywhere but was able it was available on your website and arrived in double quick time.

Quality product at a good price and find that Pirez always deliver.
