Unno’s updated Mith eMTB is one of the first bikes to use the impressive DJI Avinox drive unit.
The motor in question can deliver a whopping 105Nm of torque and 850 watts of peak power as standard, but flick it into the short-burst Boost mode, and there’s 120Nm and 1,000 watts on tap.
It also becomes one of the lightest, longest-travel electric mountain bikes on the market, weighing a claimed 21.2kg with 160mm of rear-wheel travel on tap.
Powering this is an 800Wh battery encased within the sleek carbon frame.
Its slender tube shapes hide the fact that it’s an eMTB, let alone the fact that it’ll be one of the most powerful on the trails.
Despite the cheapest bike in the range costing just over £8,000, I still think this beast of a bike will be in high demand.
New motor, more power and lower weight
While the previous-generation Mith was built around the Bosch Performance Line CX motor, the new bike is one of the first to use the DJI Avinox drive unit.
This motor offers Eco, Trail, Auto and Turbo modes, along with the more powerful Boost setting.
From a design point of view, though, it’s the compact size and low 2.52kg weight that open up possibilities for the engineers.
Powering the Avinox motor as standard is the 800Wh battery, although there is a 600Wh option if you’re looking to bring the overall weight down a bit.
In addition to the motor and battery technology, Unno has also able to make use of the Avinox's incredible integration, including the top-tube mounted touchscreen, wireless bar-mounted controllers and the Avinox app that enables you to customise just about everything you can think of.
Rider-friendly frame improvements
Unno has made changes to the full-carbon frame, built around a mixed-wheel setup.
For a start, the brand has ditched the headset-routed cables in a bid to keep things simple – and keep riders happy.
The frames are lined with cable guides to make the job of swapping hoses easier, too.
On top of that, the new rear-shock position should make setup quicker, with better access to the damper and all its adjustments.
It can also now take a coil shock, too.
Shorter seat tubes, which now range from 400-440mm across the three sizes, have been shortened to allow for longer-travel dropper posts across all sizes.
Other improvements include better chainstay and lower-link protection, along with a rubber-coated (internally) chain guide to help keep the Mith silent while you ride.
The linkage bearings are now bigger and said to be better sealed, while there are integrated fenders to protect the shock and links from rear-wheel spray.
Finally, there’s room for a 750ml bottle within the front triangle.
All frames get a lifetime warranty, too.
Refined rear-wheel travel
The 160mm of rear-wheel travel is controlled using Unno’s virtual-pivot system.
This is configured to create an extremely supple first 30 per cent of the travel before more support kicks in through the middle of the travel, hitting a controlled ramp-up at the end of the stroke.
Unno suggests two sag settings, depending on what you’re riding. You can set the shock up with 30 per cent sag for the ‘standard’ geometry setup, or 35 per cent sag in the race setup, which Unno says is ideal on steeper trails.
Anti-squat values (the amount the bike resists bobbing while you pedal) remain above 100 per cent in both of these settings.
Three frame-size options
Unno is offering the Mith in only three sizes, meaning there’s a chance not everyone will be catered for.
Reach figures range from 430-490mm.
The head angle is slacker than the previous iteration of the bike, now sitting at 63.5 degrees, and can be made slacker by 0.5 degrees if you opt to put the bike into the low setting.
We’ve emailed Unno to confirm this because there’s nothing about it in the press materials, apart from a single line regarding changes.
Seat tube angles are set at 77 degrees across all sizes, while the chainstay length remains 450mm across the board.
