For This Bike
Oct 2019
The Thunderbolt is for an experienced rider who wants to ride a rocket ship. A rider who knows how to get out of trouble quickly because rocket ships are hard to control. Get our full take on the Rocky Mountain Thunderbolt Carbon 90 BC Edition here!

This Winter we tested the $3,349 Rocky Mountain Thunderbolt Alloy 50 trail bike. For an entry level spec’d bike we were quickly impressed with the attention to detail, and features the frame sported. Video review below. Details & Specs • 27.5″ wheels • 130mm travel front and rear • Boost hub spacing •RIDE-9™ Adjustable Geometry + Suspension Rate • Aluminum front and rear triangle • Press Fit BB • Sealed cartridge bearing pivots • XS, S, M (tested), L, XL sizes The bike is fairly well refined, with a Race Face Crankset, and direct mount ring, internal cable routing, built

Not radically changed, almost conservative, the Thunderbolt stays true to its intentions.

The Rocky Mountain Thunderbolt BC Edition is guaranteed to put a smile on your face: it was by far the most agile bike in this group test.
Very playful
Beautiful frame
Comfortable suspension
The rear linkage lacks support
Nervous at speed
Small brake rotors

Like the other new bikes, you'll find blind pivots on the Thunderbolt that make for some pretty clean lines, as well as sealed bearings all around (including the lower shock mount) that replace the bushing system Rocky used previously.
Playful personality
Supple suspension action
So much adjustability
Requires more effort to ride fast on difficult trails than a 29er
Finicky suspension setup if you want to get the most out of it
So much adjustability

We spent the last three months testing the new Rocky Mountain Thunderbolt Carbon 50.

Key changes to the new carbon frame are an increase in rear travel to 130mm, plus increases to stiffness and a lowering of the shock rate curve. - Mtbr.com
