Summary

The Intense Primer is a trail bike that combines striking design with exciting ride dynamics, offering a mix of agility and traction. Its suspension is smooth with minimal pedal feedback, though some riders desire more mid-stroke support. Upgrades like the DHX2 coil shock and ENVE carbon rims can enhance performance, but they also add weight and cost.

Pros
  • Striking design and aesthetics

  • Smooth-feeling suspension

  • Agile feel through corners

  • Ground hugging feel

  • Cornering Traction

Cons
  • More mid-stroke support would help in most trail situations

  • Not the lightest carbon trail bike

  • Grips are too thin

  • Not very playful on jibs

  • Would like a longer dropper

Key Quotes
The Primer has an incredibly agile feel through corners.
BikeRadar logoBikeRadar
Intense stake their claim to creating ‘striking mountain bikes since 1993,’ and the striking part is something I personally do get onboard with.
Pinkbike
I consider the DHX2 to be the real game-changer on all the upgrades made to the build.

Intense Primer S Pro 2020 review

Feb 2020

Intense's Primer S Pro marries a 29" wheel and 150mm of travel up front to 140mm of bounce and a smaller, fat tyred 650b wheel at the rear. It's a lightweight, good looking and high-end bike that offers a lot for the asking price, but the ride and suspension isn't quite as sorted as some similarly spendy rivals.

Intense Primer S Pro first ride review

Nov 2019 · Tom Marvin

A Factory-series Fox DPX2 shock controls the Primer S Pro’s rear suspension, while a matching 36 fork sits up front.. .

Highs
  • Rear suspension is efficient with good small-bump sensitivity as well as stability

  • Full-carbon frame and bling spec

Lows
  • Maxxis Rekon+ rear tyre lacks traction in some conditions

  • I’d prefer a GRIP2-damped Fox fork, ideally
