Bike of the Week | BiviBikes Graveller

Steel for all-day adventures

BiviBikes Graveller

Following on from BiviBikes’ debut offering, the genre-blurring Malvern, the Graveller is a similarly adventurous drop-bar steel gravel bike.


Covered in mounts for bikepacking luggage and other accessories, the sturdy Graveller definitely falls at the mountain bike-adjacent end of the gravel spectrum.

What is Bike of the Week?

Every week, we bring you a detailed first look at one of the latest bikes (or framesets) to arrive at BikeRadar HQ – from road to commuting, gravel to enduro, and anything in between.

This is our chance to introduce the bike and everything that makes it unique before hitting the road or trails.

Head to our Bike of the Week hub for previous editions.

Its frame is built from skinny steel tubes and it’s matched to a simple rigid steel fork. Like the Malvern, the Graveller’s design blends gravel and mountain bike features.

The brakes are road-style flat-mount, while the bottom bracket shell is a 73mm mountain bike standard, and Bivi fits a Shimano SLX mountain bike crank.

The Graveller comes in just one size at the moment, corresponding roughly to a 55cm, which Bivi reckons is suitable for riders from 5ft 5in (165cm) to 6ft 1in (185cm).

The bike has drop bars but adopts more progressive geometry than many gravel bikes, taking a mountain bike-esque approach that should translate into more forgiving manners on technical terrain.

This entails a fairly short stack of 558mm, but a long reach (for a drop bar bike) of 409mm that pairs naturally with shorter stems.

The Graveller’s head angle is fairly slack at 70 degrees and, in combination with the fork offset of 51mm, this produces a trail figure of 77mm, which is at the upper end of what’s typical and should produce very stable handling.

Add in a moderately wide bar and you’ve got a recipe for good times in the rough – we’ve seen similar geometry work really well on bikes like the Canyon Grail 6.

For truly rowdy adventures, Bivi offers the Bunker+, which adds an additional bracing tube to the frame between the down tube and the top tube (just in front of the seat tube).

This produces a stiffer frame for carrying heavy loads, and nets you an extra set of cage or accessory mounts inside the frame.


Bivi offers the Graveller in two standard builds of which this is the slightly cheaper option. Look out for a full review in the near future.
