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

Works perfectly on my Rad Expand 5. I can now pedal over 20 mph with zero ghost pedaling! You also need the socket to remove the gear cassette. It's easy to install and made my rides far better. Love it.

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.

Sondors sends out the XS model bikes set to 20 mph and a 14-28 cog set. But you can change the settings to 25 mph but then you spin out your gears and cannot pedal fast enough, your cadence would be like 150 rpm. So I swapped it out for this 11-28 and now I can pedal to nearly 40 mph before spinning out the gears, which means it just never happens now. I love it, well built, much better than the low end shimano cog set it came with that had rusted within days here in the Florida humidity so the Chrome finish will be nice to keep it rust free as well. This is a well built quality freewheel that should work well on most of the Sondors bikes, but I can definitely assure you it works on the 2020 XS. Only caveat is on the newer 1500 watt motors the DNP tool you see here will not work. Bolton bikes sells a tool that will work. The wiring harness plug and axle bolt are too big to fit through the tool, and there's not enough metal to drill it out. I cut through mine with an angle grinder to slip the wire into it below the plug and bolt, so essentially I had to destroy the tool to make it work.

As described, quick ship, will mount and advise further upon use. A little heavy but going on e-bike, it appears to be quality made and would recommend.

This 7-speed freewheel cassette is uniquely designed for this style of spin-on hub. With an 11t-28t range of gearing it's optimal for road bikes. Easy to install with the proper equipment. Finished in chrome give a clean shiny appearance. Fit on a standard wheel hubs, provides smooth, quiet shifts. Works great, made my bikes final gear ratio is nearly 5:1. Fast, and a decent value for the money.

Wanted to eliminate "ghost pedaling" (a/k/a hamster pedaling) in the upper gears of my e-bike (Bee Cool Explorer). This was a fairly easy upgrade, the hardest part is removing the old freewheel (you need the special freewheel tool and a long breaker bar attached to it). Once this new piece installed, I indexed my derailer to the new freewheel (there are dozens of you tube videos showing how easy this is) and then re-lubed my chain. I was quite impressed with how well my chain meshed with the teeth of this freewheel and how smoothly she shifted. I've eliminated the hamster effect of pedaling at higher speeds with no effect (akin to pedaling when you're going downhill). I will say that even in the mid-ranges, I feel more leg muscles working too, an added benefit for my old bones! I opted for staying with the 28T large gear and not going for the 32T or 34T. I live in Florida and we just don't have the kind of hills to need super-low gearing, otherwise I would have gone for it.

Used this flywheel to upgrade my e-bike. Really feel the pedaling now, no wasted effort and legwork.

This Drift Maniac 7 speed freewheel was installed and professionally adjusted by the owner of the bicycle shop I've used for years. Unfortunately, this freewheel has irregular gear teeth which cause a constant grinding against the chain. This will damage the chain and cause excessive chain wear. I bought two of these 7 speed, 28-11t freewheels. I'm returning both for a full refund and buying another brand.

My Hitway 7 speed ebike came with a 14 t to 28t Freewheel sprocket. The problem was the 14 tooth only allowed the pedals to be effective up to about 18km/h. An higher speed and my pedaling could not keep up to the assist. There are lots of sprockets available on Amazon but this is the only one that i could find that came equiped with 11 tooth to 28 tooth that would fit the Hitway motor on the rear wheel. It makes such a difference, I can now pedal up to 28 km/h with the pedals keeping up to the assist of the motor. I'm very happy about this! It only takes about 10 minutes to change but you do need to have the sprocket removal tool. Ordered separately on Amazon. Quality seems good but time will tell. I will update post if I run into any issues. At this point I definitely recommend this 11t-28t sprocket upgrade!

Alles Super

Works perfectly on my ebike. Make sure you have the correct tools for installation.

Excelente para actualizar mi bici ruta, siendo yo de México llego un día antes de lo indicado, muy conforme con el producto
