After 7800 miles my original hub finally stripped out from years of rough desert trails. I was excited to find out that Biktrix had a much superior rear hub for replacement. I ordered the hub, with new spokes and new rim, all put together by Biktrix for a great price. The new Ratchet hub sounds and performs great. Now I am back climbing mountain trails again.
Blew out my original hub. Got the Wren star ratchet hub. Had a good bike shop install it with new spokes and a new tire set to boot. The mechanic commented on the quality of the hub and said I’ll probably never have another blow out. I was nervous about the fit but Biktrix had me send photos and measurements and everything fit fine.
Wren hubs are the way to go with powerful e-bikes.
I’m in my 5th year riding my Ultra. I have broken by stock hub by Oliver stressing it. The prawns can’t take my power and the 1,000 watt motors after a few hundred hard claims. So for peace of mind I bought the WREN. Now I think it’s in breakable. They have 20 teeth where the stick buns have 6 prawns. If you are a hill climber I think you should consider it.
200 Amps down low, this Wren Kit is Fn crazy strong ...
Excellent. I had a local Bike Shop Owner I've known for years restring rear wheel with you Wren Hub. I have literally torn to shreds 3 different high end sram HD Hubs and again after rebuild etc. This hub really pull alot more than it's own weight. I've applied up to 5000W or roughly 6 horse power in 6th gear that's about a 12/36/44 tooth ratio...bottom line 150lb bike 210 pound rider up to 55 miles an hr short burst and 40 mph steady and consistent reliable transport. Thanks for a great HUB. 👍 worth every cent...
I hooked this up to a POWERFUL mid-drive. ZERO issues. Im running a CYC X1 PRO GEN 2 Kit. 72v 5000W. This hub handles it.
LX was shreading hubs. 3 bearing failures in original and 2 replacement hubs. LX’s 160Nm Mid Drive motor was too much for cheap Chinese hub to handle. Ratchet hub solved that problem. Got my bike back again!!!
I haven’t tried it yet
