## Description

Quality construction makes the Royce Union RMA a mountain trail bike that performs equally well for gravel paths and for street riding. Backed by our limited 10-year frame warranty (see owner's manual for details), the lightweight hardtail frame is molded from tough 6061 heat-treated aircraft-grade aluminum and will never rust. Durable aluminum, lighter than steel, makes this bike easier to accelerate and easier to handle. We deliver this bike with the tools you need to quickly finish assembly so you can get riding. An alloy quick release binder enables easy height adjustment of the padded saddle for a proper fit. Quality matters and Royce Union makes sure that the quality of the RMA will meet your high expectations. Passionate about the outdoors; Welcome to Royce Union mountain bikes. Since 1904.

Review: I am 6'3" / 191 cm and weigh in around 265lbs / 120 Kilos. My body shape is relatively long legs , but also a lot of my height comes from my Torso. This made the handlebars too low for me so read on to see how that was addressed. Initial Impressions: Bike came on schedule and it was well packaged. There were no issues with parts missing, flat tires , or any other issues I have read about in the other reviews. The bike comes mostly assembled. My #1 recommendation is search You-Tube for Royce Union Bike assembly. I found the printed manual incomplete and somewhat confusing. The you tube video is about 12 minutes and it was perfect. Once assembled took it for a quick ride. Gear shifting takes a little getting use to, but after a few rides I have gotten use to it. I raised the seat but could not raise the handlebars. The saddle it came with was brutally uncomfortable so I ordered a new one. I also took it to the local bike shop and had a new riser (to raise the handlebars) put in. The break cables were long enough with the extension so I did not have to replace those (had I know this I probably would have done it myself). Now with raised handlebars , new more comfortable saddle it's a joy to ride so far. Other upgrades include kickstand , bell and odometer. So overall an extra $150 or so. For now very satisfied with the purchase along with the upgrades mentioned. I ride mostly roads with some trails. Bike feels solid and I am a big guy. I will update as I get more time on it.
Review: I ride this bike to work and back, and so far it’s given me almost no problem at all. Easy assembly, and a smooth ride. The only issue is that the seat was a bit uncomfortable, so I had to replace the seat with a different one. Otherwise, a very nice bike.

## Questions & Answers

**Q: What is the weight limit?**
A: up to 300 pounds.

**Q: How much weight can the bike handle? I weigh 330lbs roughly and am looking for a bike i can use to excercise in a fun way to lose weight.**
A: Royce Union  does not test or calculate the ultimate weight bearing property of its bicycles. The adult bicycles have been used extensively by riders in the weight  range of 200 to 300 pounds.
We do not have use information on riders over 300 pounds. Typically it is the dimensions of the individual that makes a Huffy product uncomfortable or unusable , not the weight of the individual.

**Q: Does the 20 inch frame fit someone 5 foot 11 inches ?**
A: suggest leg inseam would be 34-36" for the 20" frame

**Q: Will the assembly easy for beginners?**
A: Assembly is very easy. The only disappointing issue I have had is the front rim was bent and cannot get anyone to speak to regarding this. I have had to change the tube a few times already.

### ⭐⭐⭐⭐⭐ Review
*by M***L on 24 April 2021*

I really like this bike. Lightweight and a smooth ride. I use it on roads, trails, gravel with no problem. Good hybrid bike. I've ridden Specialized, Trek, Cannondales and this bike is at least up to par with the budget lines of those brands. BUT, the seat is the only thing lacking. It is narrow, BARELY padded and uncomfortable. So youll probably want to replace that, which is fine since you can get seats for cheap and installation is easy.
