Razor RSF350 Single Speed Electric Bike w/ Pneumatic Tires & Chain Driven Motor

My son is 9.65lbs and this bike is his favorite!He would ride all day if let him. It runs great on grass, dirt and the road. The best is obviously the road but I was shocked at how great this thing did in the grass. I've had no problem with the battery life of it but then again he usually only rides it for about an hour at a time and he always plugs it in afterwards so we've never had it die on us. It comes fully assembled all you do is put the handle bar on, super easy it took 5 mins. Would definitely recommend

I purchased this bike and as soon as it arrived my kids started to beg to ride it! By son rode it first with no difficulty. This bike is easy to ride and is fun to ride.Pros good for kids , easy to ride, fun to ride, safe riding speed, good deal,Cons absolutely nothing!I suggest that if you are interested in buying this bike, then it’s a good deal.

Got this for a crazy good price during a price drop and knew the issue about the front bearings. Sure enough, they started to go bad, but well after the warranty was up. Found a set online for $10 shipped. Easy to replace so no big deal. My guess is the nut on the axle was torqued down way too tight, pressing the spacers in-between the forks into the bearings... Over time they fail. With new bearings and the axle nut less tight, the front wheel spins much more freely.Otherwise, son loves this motorbike. He is 7, 43 lbs. Charge lasts a long time. He rides with his cousin who has the Razor scooter. Neighbor kids also ride his motorbike... Easy to work on.

My son LOVES his motorcycle. The recommendation is for 14 yr olds but my son is 8 and it's awesome for him and he rides it without any issues. My daughter even rides as a passenger. I can't imagine a 14 yr old riding it since it's very small. Overall we all love it. It has been his favorite gift.I guess the only thing that I don't like is that it doesn't hold a charge for very long. I think it's like 30 mins or something. But this also keeps him more active since, while it's charging, he rides his regular bike.

I think the platform is good but I really dislike the binary full-on/full-off throttles that Razor uses in some products for small kids now-a-days unlike some of their earlier models of the same name from years ago that came with variable speed throttles. This RSF350 unfortunately also has a full-on/full-off "twist grip" throttle. I have decided to replace the stock throttle and motor controller on this RSF350 with a variable speed aftermarket throttle and controller right out of the box, (I have used aftermarket controller and throttles in the past to add variable speed control to newer e100 and e300s scooters, and an mx350 dirtbike, making them all more user-friendly, way more enjoyable to use, and much safer in my opinion). I was surprised that the criss-cross bars on the side of the red "tank" of the RSF350 are just plastic for aesthetics and not metal acting as a structural part of the frame. The pics show the frame being highly polished including these criss-cross members over the tank. It isn't. The frame is painted gray (I've included a pic to show the actual frame). The rear caliper is welcome as compared to the MX350 which had a band-like brake but the brake pad on my RX350 dragged on the rotor disk in one spot every revolution out of the box. With some fiddling I was able to adjust it out for the most part. If it rubs lightly now I expect it will wear the brake pad in. The user manual doesn't go into enough detail on how to adjust the caliper but I figured it out with some tools and some tinkering. I'm happy with my purchase but in my opinion Razor's products would be SO much better with variable speed control from the factory. I think it is a nice platform and am glad I bought it but intend to change it. Once I add an aftermarket variable speed controller and throttle it will be ready to give to my kid.

Scam! Purchased for my grandson, total crap, he was so disappointed. The specs said 14mph didn't even go 2mph, won't fully charge, and the seller said there's nothing they can do. Purchased another from Best Buy, no issues there.

The recommended age is 13+ but after reading other reviews, I bought this as a Holiday gift for my son. It is easy to ride. He is comfortable and confident. Not scared. He loves it. It can last for over an hour with light use. But he often lets friends ride it and sometimes 2 riders at a time. Like a 10yr old and 3yr old together. Or my son and a 6yr old, together. The extra weight of 2 passengers causes the bike to obviously go slower, but it also causes the bike to die in about 30-40 mins. Which is probably why it doesn't last long for the recommended age group. The weight puts too much strain on it. It's perfect for a younger kid who can use it with safety and responsibility!

First ride report: HOLY CRAP THIS IS SOOOOOO MUCH FUN. Plenty of oomph, 30min of full throttle use, and after a few hours we squeezed another 20min of riding, and me and my friends are 170lbs. Solid, fun machine. Runs pavement, dirt, rocks, grass, no problem.Yes it's tiny- just look at the pictures, but it is an absolute blast. Just picked up another one in fact.Will update as time goes on.
