DRIFT MANIAC 7 Speed Freewheel For E-Bike 11-28T/11-34T Screw On Freewheel

Fitted to my ebike stopped the problem of pedalling like mad at higher speeds

Used this to replace a Shimano 14-28 seven speed screw on. Worth noting that it’s almost identical in terms of spacings in relation to the wheel hub, but not quite. I got around this by adding a thin washer as a spacer on the wheel axle, but I guess you could also adjust the derailleur to compensate.The gear itself appears well made and behaves well when shifting up and down. The additional range compared with my old Shimano 14-28 is very noticeable (and welcome) as I often found myself unable to pedal fast enough to maintain high speeds on those occasions when either going downhill, or when I have a decent tailwind.Time will tell how durable it is, but so far so good.

Price reflected in quality..1 still going strong working good...2nd has lasted only 400 miles and is clacking like mad...stripped sprocket down but cant re grease it..having to buy a replacement now..hope this lasts longer

I've fixed up an older commuter eBike so that my partner can keep up with me on the road. Nothing too far, or busy roads, but some sections were far to steep for the motor and the single speed 14-28 to cope with compared to my 11-42 compact. This was the widest-ratio direct-replacement 7 speed freewheel I could find, but after fitting (which was rather difficult owing to the eBike wiring) and readjusting the rear mech, the bike shifts smoothly and has a much lower 'climbing gear' for some of those unavoidable steep sections.I haven't had much of a chance to see whether the 14 > 11 T change helps with the ebike's assisted top-end speed (it's an older model with no limiter), but I am happy with the purchase and suits the bike nicely. Solid construction, so hopefully it'll stand up to the rider+motor torques as advertised over time.

on time and does the job its designed to do

I do a lot of combined Off & On road Moutain Biking. When on the road sections down hill I need more speed but on my standard sprockets I'm maxed out.Wow what a difference the 11t & 13t sprockets make but still have the large 34t sprocket for those big hills . On the standard sprockets set's that only go down to 14t sprocket, my MTB used to get ahead of my leg. My bike goes faster than my legs can pedal on those big down hill sections (on road). Now I can drop down another 2 gears. I get so much more speed & I can keep powering down those hills without my bike over taking me. The hills by me generally run out before I do. Just a No brainer if you get maxed out for speed as I was.

I have used this cassette on my e-bike for nearly a year.The design of this cassette seems to be quite crude and basic compared to others. Neither I or two bike shops could get my Shimano Tourney or Altus derailleurs to line up with this cassette. After adjustment it would be fine, but a few miles of riding and the alignment was out and the gears started clicking, jumping or slipping again. The gap between the cogs has altered as well, so it looks like the cassette was starting to come apart. The gear changes have never been a smooth as my other bikes or the original factory fitted cassette, which was an unknown make.Have now changed the cassette to a Shimano Hyperglide version, and the gears have stayed aligned for several months so far with no issues.Maybe my experience was a one off, but I will not be buying or recommending this product or buying it again.
