CYSKY Single Speed Crankset E-Bike Crank 170mm 130 BCD 48T/53T/56T/58T/60T Square Taper Bike Crankset for Folding e-Bike Fixed Gear Track Road Bike

I have an AddMotor 500 watt Ebike and it cruises at 25mph which is too fast for me to keep up with using the stock 40 tooth front chain sprocket. I wanted a slower cadence so I went with the biggest front sprocket I could find. This one is perfect, my cadence is about 60 RPM now so I can comfortably pedal at 25 mph and add assistance to the motor. I used a wheel puller to remove the old crank set and this one bolted right on. I see other reviews stating this is weak, I do not see any weakness or straightness issues at all. Although this crank set is lighter than the stock I have not had any issues in 60 miles. My riding is fast cruising on bicycle trails. I have yet to extend the chain but have the parts on order to do so and then I will try gear changing. Right now I leave it in top gear and let the motor do most of the work accelerating up to speed, it doesn’t take long. The price was unbeatable for testing out a theory and it exceeded my expectations, it is a beautiful piece of workmanship as well. My 66 year old knees are a lot happier now and I am getting a good workout while feeling like Superman ( even though I’m definitely not)as I pass everyone on the trail.

This is my second round with this chain ring. It's the same size as a dinner plate. It's very strong. These cranks are 7075t6 grade aircraft aluminum, so there pretty strong, and very light. If you end up bending your chain ring, chances are your bottom bracket it's self is bent. I've put over 12,000 miles on this crank with no problem in the past year. There better for cadence, to keep your rpm down, while getting the same speed on less watts, I can pump out over 850 watts on this ring with no problem in performance, so if your looking for a track crank, and not wanting to spend 150 to 400 bucks, this is the crank for you. Now on opening the box, I noticed 2 teeth had some flat tip damage, which is fine, it just the tip, filed down the sides, and it's good. As cheap 60tooth cranks go, your not gonna find one any better.

I replaced the crank that came with my e-bike. With this one, I still get tension on the pedals at around 32mph, which is exactly what I wanted. Good quality, sturdy. Been using it for several months with no issues.

Um, I bought it for the sprocket side which was excellent! But the other side, I tried for hours to get a peddle to thread into it. Luckily it's not why I bought this so. 4 stars, other then that it's great.

Nice quality and undamaged upon arrival.

This is a quality crank that works perfectly with square taper bottom bracket e bikes. I purchased the 60 tooth that has a more webbed chaining design stiff great looking.

Good news. The 53T model fit and works on my Magicyle Ebike. No more ghost pedaling at ANY speed. I love it. The bad news is the left crank arm hit the frame rail a little bit on the way by when pedaling. The crank arms obviously are a different shape than the stock Magicyle’s. The right crank arm barely clears the frame. Can’t have that happening as it will drive you crazy. I took my grinder to the end/back of the crank arm until it cleared the frame, and then repainted it black. Actually not that big of a deal. Definitely worth the trouble for the end result for me.

Gapping is awful, the teeth do not align with my chain links, it's lighter then I expected though, it's meant for light work, not heavy climbs. Which is ideal for ebikes, however the measurements between each tooth are completely off. Terrible measurements. And no, I checked the chain, while it does have some patina it's not stretched. I even proof checked it by sticking the stock crank back on to make sure. It fits fine on the stock. It slips off them moment I get to 20mph.

So far so good , light and durable. Will update after multiple uses

海外からという事でしたので、梱包がグチャグチャになってるのかなぁと思いましたが、全くもって普通の梱包でした。 気になる中身の梱包も一つ一つがプチプチに包まれており梱包物の下にも紙が敷いており丁寧感が伝わってきました。 本体は、思っていたよりかも大きくしっかりとした造りがあり、塗装剥がれもなくバッチリでした。 参考程度に写真を掲載しておきます。
