RSD Bikes – The Mayor Fat-bike Enters the Scene!


The Mayor is in the house! One of the newer members of our test fleet comes to us from north of the border in Toronto, Ontario, Canada and is sold by RSD Bikes, a relative newcomer to the bike scene, established in 2012.

Right out of the box the The Mayor went together well with a few ogle worthy parts like the house brand Carbon Fork and Race Face Turbine crank getting some attention as well as some nice frame details like ISCG-05 Tabs and Dropper Post cable routing.


It is spring time here in the Upper Midwest and that means varying conditions are the order of the day. Jim and I have been swapping rides on the Mayor with the first few rides being a cross between Urban Assault and local trails where the conditions vary from day to day depending on whether the temps were above freezing or below.


The single chainring set up in the front has a narrow/wide chainring to keep the chain in place and the 190mm rear-spacing make for generous chain clearance. The frame clearance with the stock Vee Tire Snowshoes made us hanker for a try with the current big boys of fat, Bud and Lou. Guess what, they fit! Just barely but they do fit. If you do decide to run the Bud/Lou combo taking a razor to the mold whiskers will help a lot.



So, after a few weeks on “The Mayor” we are really enjoying the bike. While the geometry numbers look similar to several other fat-bikes I find that this bike has a very playful ride and has done everything I’ve asked of it and more. Several of our rides could almost be described as “riding on the moon” with the still frozen ice shelves off the coast of Lake Michigan. With the Bud and Lou combo mounted up the Beach rides have been a blast in the frozen waste land between open water and the frigid shore.

With more ride time needed on the Mayor we decided to swap in a pair of prototype Vee Tire H-Billies and that is where we are today. Looking for more time on a very fun fat-bike!

Our test bike did not come equipped with rack mounts although Alex from RSD informs me that there are plans to add them in a future run. Frankly, I see this as more of a play bike than one to get lost on in the wilderness but if that kind of riding is your bag, just use bags! Seat Bag, Frame Bag and Handlebar Bag.

  1. Hey, that’s my bike! LOL. I talked my boss at our shop into carrying these guys, as we were not even into fat. Scored one in a medium, and it’s the most fun I’ve had on a bike in FOREVER! Being my first fatty, it’s hard to compare honestly, but this thing ROCKS. I am loving the quality and the spec, specially for the price. I’ve dolled mine up a bit, and it’s a bit more of a head turner now as well. Been on it for a month, and no issues to report as of yet. Still smooth, quiet and tight. Glad to see Bud and Lou can be squeezed on there. Oh, and as a side note, Alex is an awesome dude. Great bunch out there at RSD. Shameless plug over.

  2. My bike too! Can’t say enough good about this ride. Wanted one back in Dec ’13 but had to wait till March to get my hands on it. Best bang for the buck anywhere. Unbelievable parts spec for the $$$. Fantastic ride quality. No regrets! Buy one… if you can find one.

  3. Hey guys,this is one great looking bike!Was wondering with rockshox bluto coming on the fat bike scene any plans for future to have one on mayor?

  4. Looks like a nice bike. What rims are on there stock? What rims where the Bud & Lou combo mounted on?
