Trail and Enduro Bikes


Mojo and Nicolai have pioneered something special with their collaboration. Progressive and up to date geometry is much talked about these days, with words such as long, low and slack being thrown around on a regular basis. has any brand moved things forward as much as we see here though?

It’s only after a good few years of testing, evaluating and pushing their thinking that bit further that the Mojo team settled on the design that we see here in the GeoMetron G16.

The creativity is down to Chris Porter and his team at Mojo, who had been tweaking frame geometry as well as suspension tunes, firstly with the stock Forward Geometry Mondraker bikes and then onto prototype frames built by Nicolai of Germany.

‘If a slack head angle, low bottom bracket and long wheelbase is better, faster and safer, then why not keep going? Can it be even better, even faster and even safer?’ – that’s what Chris and his team asked themselves.

Nicolai have been hand crafting their custom aluminium frames for years now and the Ion 16 was the starting point for this bike, a frame with 160mm of rear wheel travel and running on 27.5”/650B wheels. With the Mojo team working closely with Nicolai and using their experience with Fox suspension, they created the G16/Geometron. With the Mojo sizing, geometry and suspension tune, this frame has 155/175mm of rear wheel travel (depending on rear shock) and sits between the G13 29er and the G19 DH frame in the range.

‘The Geometron’s strength is very much on descending with a long and low chassis, as well offering incredibly stable climbing’

With a head angle of between 62 and 63.5 degrees, depending on fork choice, and a ‘low as they dare’ bottom bracket height of around 340mm, these figures certainly are outside the boundaries of even the most up to date enduro bikes. But that’s just the start of their thinking. Mojo added much more length into the frame, giving better pedalling position over the cranks when climbing and allowing a roomy reach when paired with a sub 50mm stem. A very steep seat tube angle works with both the frame’s sizing and the Nicolai suspension design to give both better climbing balance and traction. The overall centre of gravity, of rider and bike, is further forward, giving better traction at the front wheel in all cornering situations. The result really is a bike that is not just capable in all descending situations (as you would expect with a modern long travel bike) but climbs with great authority too. The sizing, for those riders struggling to find a bike long enough, is a game changer too.

With five frame sizes available, there is absolutely no compromise when it comes to getting the right fit. With the talk around these frames having a heavy emphasis on taller riders at six foot and over, the reach measurements of the three larger frames (520, 535 and 555mm) are figures not seen on other production bikes and really head into new territory. An XL size Mondraker Dune has a reach of 508mm by comparison.

The smaller two sizes should not be overlooked though. With suitably short seat tubes (420mm/16.5” and 440mm/17.3”) there’s no issue with fitting a long travel dropper if you feel the reach measurements of the frame could work for you. These two frames are built around slightly shorter 445mm chainstays too, showing Mojo’s thorough approach to the details. All the G16 frames now have a revised rear swingarm and Boost 148mm dropouts.

Mojo/Nicolai Geometron G16

If you need convincing on this way of thinking then Mojo have that covered too. It’s a complete package on offer here, with a comprehensive approach to testing and dialling in a Geometron frame or bike. An in-depth half day test can be arranged where you get to evaluate the best sizing, shock tune and bike set-up (stem length, bar width, crank length etc) for your needs. It’s a typically no-compromise approach from Mojo – here they are offering not only an innovative frame design but one built with longevity in mind and set up perfectly for your requirements.
