  • wow!
Color: Silver Size: 18-Inch Wheels Style: L18 Pattern Name: Bike
all the negative reviews had me worried. BUT none of those problems applied to our bike. no brake problems, no missing parts, nothing wrong. my wife who barely remembers righty tighty lefty loosy put it together in 20min. brakes were pre-iinstalled, literally all she had to was put on the handlebars, the front wheel, and the seat. my son is 3'9" and is just big enough to ride the L18 with 18" wheels. to top it all off i bought the damaged box deal for 160 vs the 250+ regular price ... show more

  • Extremely Easy to Assemble. Bike Looks Amazing. M8x1.25 Tap May be Needed.
Color: Orange Size: 20-Inch Wheels Style: Mag Pattern Name: Bike
The bike from the pictures looked pretty cool. I didn't realize how beautiful this bike would be until it came in the mail. I purchased the Legion Mag in orange for my 8 year old. It was great to see his reaction on Christmas when receiving this bike. He was so excited. I read some other reviews from reviewers who had complaints on the difficulty of assembling the bike and in my opinion the people having trouble assembling the bike must be blatantly ignorant or illiterate. The instructions for assembly are written so a teenager could assemble this bike, with clearly labeled diagrams and more in depth explanations than what is necessary for assembly. The instructions on assembly are excellent and I had almost no trouble assembling the bike without them until it came to adjusting the brakes. I assembled the entire bike without instructions except for the brakes because it is just self explanatory. I was also able to assemble the brakes without any trouble or needing the instructions although I did refer to them for proper adjustment and alignment protocols. The only issue I had when assembling the bike is when I got to the point of attaching the handlebars to the handlebar binder assembly attached to the stem. The four socket cap screws that tighten down on the handlebar binder bracket would not thread easily. I felt as though I would break the screws or destroy the threads if I attempted to tighten them down far enough to grip the handlebars. There was too much paint in the threaded holes and also the tolerances on the machining of the threads was not great. I have included some pictures showing just how much paint was removed from tapping and also chips from burs in the threaded holes from poor tolerance drilling and tapping at the factory. In order to fix this problem I grabbed a tap handle and a M8x1.25 normal thread tap and tapped the holes. I would give this bike a 4.9 out of 5 if I could just because I needed to tap these holes and a tap was not listed as a required tool. I don't think many people will have problems assembling the bike even if they have this issue and need to tap the four holes as these are the only holes that need anything to be screwed into. Honestly if you don't at the very least know how to use a tap and die set you probably shouldn't be assembling a bike as it's not safe to do so if you're not familiar with basic tools. You could wind up hurting your child from pure negligence if you don't know how to use basic hand tools to assemble this bike properly. My suggestion is that you take it to a local bike shop and pay $30-$40 to have them assemble the bike and adjust the brakes if you don't know what you are doing. I assume some people who buy this bike will do just that with the majority of people knowing how basic hand tools work and them being able to assemble it themselves. Overall the bike is amazing, my son loves it, it was extremely easy to assemble, and I recommend you tap the holes on the handlebar binder even if it doesn't need it as it will allow you to make a more secure connection. Please don't listen to people complaining about difficult assembly as it was extremely easy even the detangler brakes something of which I've never seen or dealt with on a bike before. The instructions are very clear on how to hook the brakes up and how to adjust them properly and I was actually surprised how easy it was to assemble the brakes because I was expecting something very difficult based on the reviews but it turns out these brakes are easier to assemble than normal brakes. ... show more

  • All good but brakes need improvement
Color: Orange Size: 20-Inch Wheels Style: Mag Pattern Name: Bike
Great bike east to assemble but Had to take to a bike shop to see what was up with the brakes. Hand brake was hard for my child and would barely stop , i upgraded the pads and that helped.

  • Cutting corners
Color: Silver Size: 20-Inch Wheels Style: Mag Pattern Name: Bike
The instructions do not match the product. There are no videos or anything on assembly. And why is it every bike or scooter I buy for my children these days is missing parts? So far, this is missing a lock nut for the handlebar assembly. I spent $300 on a bike with the wrong instructions and missing parts. The quality of the bike itself is fine, but I feel like assembly would be much smoother with better instructions and all the necessary pieces. ... show more

  • Excelente bicicleta
Color: Black/Teal Size: 20-Inch Wheels Style: Legion L10 Pattern Name: Bike
Una bicicleta de buena calidad, mi hijo tiene 6 años, antes de esta bicicleta ya manejaba sin ruedas otra más pequeña. Así que le ha ido bien, solo debe acostumbrarse a frenar apretando el gatillo en el volante y listo. La recomiendo y su e tregua fue rápida y buen precio para la calidad de la bici.
