Mongoose has released a new line of bikes called Guide built for commuting, gravel (or all road, or groad) riding and bikepacking. Three models are available and they all roll on 29 x 1.75in tires for capability on and off the pavement.


In addition to the wider tires, the geometry of the Guide series is a bit more relaxed and upright for long days in the saddle and fully loaded touring.

The Guide series starts with the Sport.

Drivetrain duties bump down from its more expensive siblings with a Shimano Sora 2×9 drivetrain and Samox cranks.

Interestingly, even with less gearing, the range is a bit broader with 48/32 chainrings and a 11-34 cassette.
