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

Met my needs

Perfect upgrade for a 7 speed freewheel for any geared motor ebike This thing combined with the 52 tooth front chainring on my ebike lets me pedal at a steady 37 mph and still feel resistance in the pedals in 7th gear it could even go faster if I could pedal faster, even the lower gears are improved 6th is good for 30+ mph, 5th for 25, 4th for 19 all actually letting me put in effort at various pedal assist levels for example pas 3 on my bike cuts off at 24 mph 5th gear lets me pedal at 25... so the motor only kicks in if i drop below 24. improving efficiency. it's even better at lower gears and settings because the motor uses less wattage when it is needed.

My e-bike came with a 14-28t freewheel. I was ghost pedaling at 20mph. Switching to this 11-28 freewheel totally solved that problem. I can manage reasonable input above 28mph now. This was a great first step. I was also going to change my front chain ring from a 42t to a 46t, but held off because I would have needed to replace the whole crank set and get a larger chain. I’m glad I waited because just changing to a freewheel with an 11t vs the 14t made a huge improvement. I’ve only had it on for a couple of weeks so I can’t speak to the longevity. No problems yet and the install was easy with the optional removal tool they sell. The opening on the tool was the largest I have seen and I think will accommodate most quick release motor connections. Now I can still get exercise while traveling quickly. It’s good for keeping up with traffic or using less watts to extend my range in peddle assist 4 or 5.

Big improvement on my ghost pedaling.Installed on Bee Cool Ranger e-bike

I haven’t used it yet.It seems like someone found Shimano’s tooling for the rare & discontinued “Mega 7” that is written about and pictured on Sheldon Brown’s site, and, with or without Shimano’s permission, resumed production.But the edges of the cogs and the surface finish appear to have missed some finishing steps before chrome plating that Shimano wouldn’t let fly on their $10 freewheels or cassettes.It probably will work fine. It is definitely too wide to be using on a wheel laced & spaced for 5 or 6 speed.

Fit on my Lectric 3.0 like it was made to be. I pull the dog in the trailer. 1st gear is nice now. Get the socket as well

Primeras impresiones. El piñón funciona muy bien en una bicicleta normal. Utilizaba un piñón 14-28 El cual era más lento. Con este se gana más velocidad. Pero también exige tener un a buena condición física para poder moverlo

I bought this freewheel almost two years ago and remember how frustrated I was because I had spent a lot of time and simply could not get the 11 teeth sprocket work without slipping. I kind of stopped using the bike for a good year year because of that but recently started over and even bought a new chain (the old one was not worn) and still no success. First of all, as shown in other reviews, the teeth are oddly shaped and partially almost completely missing. That is the case even on the 11 and 13 teeth sprockets, even though it is clear that for these the entire chain tension is carried by only maybe 7 teeth, and yet they still put in these stupid rounded and way too short teeth. Now after replacing the chain (and the old one had accumulated a bit of dirt on the grease) I can clearly see to the side of the 11 teeth sprocket that the chain was in fact running on the freewheel shaft, instead of on the 11 teeth sprocket itself, I can clearly see the grease spots from the chain on the shaft, and the wear. Again, the brand new chain did not help here, it maybe made is worse, as it seems to slip even more. Overall, this is just a stupid design. It is possible that 11 teeth sprockets can work, if the freewheel shaft is smaller in diameter, or if there's normally shaped teeth, but the way they sold this, it just cannot work properly - by design!
