Review: Extremely Easy to Assemble. Bike Looks Amazing. M8x1.25 Tap May be Needed. - 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.
Review: GREAT BIKE! HIGHLY RECOMMEND. - I assembled it today and it took 20 minutes tops. If you have ever assembled anything before then it should be fairly easy. I didn't open the manual for instructions besides confirming my suspicion of which direction the large washers with the raised ridge were orientated. The raised edge goes inwards towards the forks FYI. The brakes were very easy to adjust, I seen reviews stating how difficult they were to adjust or setup. Not sure why but they couldn't be a more basic setup. I also recommend making sure the bearings in the fork tube are not to tight. The ones on the bike I received were WAY to tight and you could physically feel individual bearings moving when you turned the handlebars. After adjusting accordingly it moves nice and smooth. I saw a review that their stalk broke and this could be why it broke. If they are to tight you can damage them and eventually the stalk as well. I definitely recommend this kids freestyle bike. Brings back memories of my bmx bikes back in the 80's. The orange color is awesome as well. Especially since my grandson is a big Oregon State beavers fan.

## Questions & Answers

**Q: Is there a way to adjust the distance of the handbrake lever to the handle bar? My sons hands can clasp it safely and the screw on the side doesnt do**
A: There is a reach adjustment screw which is a small phillips screw. That'll move that lever closer and further away from the handelbar. Thanks.

**Q: It says this typically ships within 1 to 2 months. How soon should I expect this item to actually ship and will it really take up to 2 months?**
A: I ordered when it was in stock showed up within 3 days.  It could take the whole 2 months, as shipping sucks lately and also the 18" bike has been backordered in multiple brands for a while now.

**Q: Can u put a bigger seat on it so it’s easier to sit and pedal?**
A: I would say so.  It’s a skinny seat for tricks my grandson said.  He’s 9.  Lol

**Q: Why did my bike come with no pedals**
A: Hi. We're sorry to hear that. Within the product's one-year limited warranty, we'd be happy to provide replacements for pedals that were missing. We ask you to please reach out to us at 800-626-2811, Monday-Friday 7 am-6 pm CST. We are also available via DM on Facebook, Instagram, and Twitter. Please have your bike’s model number and date code handy. These can be found on a black and silver sticker on the frame above the pedal area. Warm Regards
