OTSO VOYTEK v2

• Lightweight Carbon Hardtail FAT bike

• Designed for up to 120mm travel suspension

• World’s narrowest FAT bike Q-Factor

Release date: 19-SEP-2023

The Voytek 2 feels more like riding a mountain bike than a bike built for (up to) 26" x 4.6" tires because it has a narrow Q factor. The Q factor of a bike is the distance between the outer surfaces of your two crank-arms. The narrower the Q factor, the more natural it feels to pedal and handle the bike because it is closer to your normal biomechanics. It also allows for stronger power transfer to the pedals, more efficient pedaling, and increased overall performance.

Adjustable Geometry

When pairing the GeoChip head tube system with the Tuning Chip rear dropout system, Voytek 2 geometry has unprecedented adjustability.

• Pair a long wheelbase with a slack head tube angle for a stable ride in deep snow.

• Pair a short wheelbase with a steeper head tube angle for a responsive ride on packed, tacky snow. Or mix and match based on your riding style.

Customize Reach and Head Tube Angle

GeoChip is a new integrated system that allows you to adjust reach and head tube angle. Three sets of flip chips nest in the frame and hold the headset upper and lower cups.

• One set of GeoChip flip chips allows for +/- 10mm of reach adjustment, another allows for +/- 1º of head tube angle adjustment, and the third allows for +/- 2º of head tube angle adjustment.

• This means that you can easily adjust your reach or head tube angle at home based on the riding ahead.

• With two reach options for each bike due to GeoChip, Voytek 2 effectively has eight frame sizes.

Tuning Chip Rear Dropout System

All Otso bikes are equipped with adjustable geometry via our patented Tuning Chip rear dropout system.

• The Tuning Chip can adjust the wheelbase by up to 20mm, raise or lower the bottom bracket by up to 4mm, and adjust the head tube angle by +/- 0.5º.

• With the machined aluminum flip chip in the rear position, Voytek 2 has a longer wheelbase, lower bottom bracket, and slacker head tube angle for confidence and stability in deeper snow.

• Use the front position for more responsive handling on packed trails with tight turns. A middle position chip pairs the best of both worlds.

Tire Clearance and Wheel Swapping

A full breakdown of tire/rim pairings can be found below in the Tech Specs.

• Voytek 2 can fit (up to) 26” x 4.6”, 27.5" x 4.5", or 29” x 3.0” tires tires on stock rims.

• To achieve this wide tire clearance with an extremely narrow bottom bracket, the rear hub has a 5mm outboard offset to prevent chain rub.

• So when the trails are packed with snow, ride 26” x 4.0” tires, then when the snow melts and the trails turn to dirt, swap in your 29” wheelset for plus mountain bike riding. Voytek 2 was designed to accommodate multiple wheel sizes without compromising ride quality.

Modern MTB Geometry

Voytek 2 builds on the geometry that Otso pioneered with our original Voytek.

• Otso gave the Voytek 2 a slacker head tube angle, steeper seat tube angle, shorter standover.

• This updated geometry allows you to go faster with more confidence.

Suspension Correction

The Voytek 2 has a suspension corrected frame. This means that you can build it with a 120mm travel suspension fork without drastically changing the geometry of the bike with a rigid fork.

Dropper Compatibility

Dropper post routing has a fully internal sleeve via a port behind the head tube. The Wolf Tooth Resolve Dropper Post is an option on the Voytek 2 Custom Bike Builder.

Large Front Triangle

A larger front triangle means that you can fit more cargo for your ride. Use this space for a custom frame bag, two bottles, or anything else that you need to carry for the ride ahead.

1. GeoChip

Headset flip chip allows for adjustable Reach and integrated Head Tube Angle (HTA) adjustment of +/- 1º and +/- 2º.

2. Slacker Head Tube Angle

A head tube angle of 68º is 1º slacker than the original Voytek.

3. Steeper Seat Tube Angle

Updated Seat Tube Angle (STA) of 74º is 1º steeper than the original Voytek.

4. Improved Tire Clearance

With a rear hub offset of 5mm, Voytek v2 can clear (most) 26” x 4.6” tires without interfering with 12-speed chains, at 10 PSI or lower tire pressure, on 85mm or narrower rims (according to OTSO).

8. Rear Hub Offset

The rear hub has a 5mm offset to the non-drive side to help with tire clearance and chain rub on 12-spd drivetrains.

9. New Paint

A new paint and decal layout with three different colorway options.

10. More Mounts

Additional threaded mounts make it easier to add bags and racks to the frame without straps. (Including new Top Tube mount!)

11. Longer Effective Top Tube & Reach

The Voytek v2 has a longer Effective Top Tube (ETT) and Reach than the original Voytek.

ETT increase = 15-25mm

Reach increase = 28-39mm

Wheelbase increase = 36-48mm

• *For wheel/tire combinations not listed above, the max tire width should not exceed 105mm if you are running 12 speed, should not exceed 108mm if you are running 11 speed (or less), and clearance to the frame should never be less than 6mm.

• **Tire width and runout can vary by a couple millimeters, and tubeless tires will stretch slightly over time. Wheel dish will also affect chain clearance.

• OTSO MFG tests were performed with new tires at 10psi on wheels dished 5mm to the non-driveside.
