Carbon Generation. The rise of a new era.

Carbon creativity
Dedicated enduro geometry
Italian design

Experience a new level of riding

The Gram was born for THOK-style E-Enduro: this includes breathtaking downhill trails after you’ve tackled the most technically demanding climbs. Full carbon provides a new lightness, maximum rigidity, extreme flexibility. The Gram marks a historic turning point in Enduro THOK E-Bikes. And now we’re reaching the next level, nothing will be the same. Performance First, again and always.

Design

IN NAME AND IN FACT

A strong, firm and determined spirit. Gram is Piedmontese for “mean”. No matter how steep the downhill trails or rough the climbs may be, the Gram will take on any trail with grit, reaching all summits and dominating every slope.

EXCELLENT PERFORMANCE

The Gram has been designed by Aldo Drudi’s D-Perf. With style enhancing the bike’s performance, Aldo has harmonised symmetry and asymmetry, he has struck the perfect balance between aesthetics and technicality. He has won many awards, designed helmets for many famous Grand Prix motorcycle racers, and has made the Gram an iconic representative of the prestigious and refined Italian Style.

Carbon: high-performance creativity

With its Gram, THOK E-Bikes enters the high-performance carbon world: with carbon fibre you can create many different, complex shapes and harness your creativity.

Uniqueness

Quality material, as well as the Gram’s lay-up and design have been devised and developed by THOK to be combined with very efficient geometries that ensure a perfect balance between flexibility and rigidity.

UD carbon’s lightness

The unidirectional arrangement of the carbon fibres (UD Carbon) allows them to be excluded in areas where they are not needed because they are not used. This means:

more thickness at the points of maximum stress, less thickness where it is not needed. This ensures the Gram's absolute endurance for Enduro use, maximum lightness, and at the same time extraordinary rigidity and riding comfort.

DISCOVER MORE

A combination of rigidity and flexibility

The Gram frame includes “high-resistance” carbon (more resistant, less rigid) and “high-modulus” carbon (more rigid, less resistant).

Their balance in the distribution within the frame has been assessed through the use of FEM tests: angles, curves and junction points have been reinforced to ensure maximum resistance and flexibility: the motor area, head tube and rear stays are extremely rigid.

DISCOVER MORE

Full Carbon Comfort and Perfection

The Gram is a true “Full Carbon”. All the pads on the frame are positioned directly onto the carbon

without aluminium bushings. This provides greater rigidity and solves problems caused by friction and wear.

DISCOVER MORE

E-Enduro Customised Geometry

By using carbon, Gram did not need to make any structural compromises. Its geometry was developed with a “zero limits” mindset. New angles, new lines, new shapes, excellence. From riders for e-riders: the lines of the frame are the combination of all our know-how, our many years of experience as passionate riders, our pursuit of adventure and freedom. With the Gram you will ride on undreamed-of trails, Enduro will no longer have any limits.

 

Explore what makes each ride unique

Angles are major players in frame design. Even a small degree difference will alter your pedalling and riding position, traction and riding precision, as well as safety and comfort.

 

The Gram’s seat tube has been verticalised with a 78° angle to ensure maximum pedalling efficiency and extreme traction on climbs, as the rider’s weight is shifted forward (preventing bike wheelies). It has an open steering angle of 64°. This enables the bike to go over obstacles without stumbling (avoiding OTB-Over The Bar) and, thanks to the advanced off-set, makes the bike both easy to handle and stable.

DISCOVER MORE

Perfect rear asymmetry

The full carbon rear stays have asymmetrical rectangular lower chainstays with integrated cable routing. A frame construction masterpiece. This provides unprecedented rigidity, as well as maximum traction on climbs and extreme responsiveness when riding downhill.

T-Front System

The Gram’s innovative steering area features the Big Eye at its centre: simple and perfect magnificence.

The BIG EYE is the beating heart of the Gram: it is one of the elements on which THOK's research and development centre has focused the most. It decreases the load in the head tube area during use on very bumpy enduro trails, while still guaranteeing maximum rigidity and steering precision, also thanks to the use of the 1.8” tapered head tube and FSA headset specially designed for THOK E-Bikes.

DISCOVER MORE

Down tube “Exagon“

The Exagon down tube features a complex carbon system with multiple degrees of thickness.

Its sharp 'C' shape, along with the Big Eye, helps disperse tension when used on very rough terrain. It is extremely verticalised to lower the centre of gravity and is home to the removable 630 Wh Shimano integrated battery.

DISCOVER MORE

Viper Head Plus Top tube

A true E-Enduro force of nature, the Gram has a Viper Head Plus top tube with a headset recess.

This provides a lowered position for the handlebar area and consequently a more forward position for the rider on the front end. In other words: maximum riding stability even in extreme E-Enduro sections. Thanks also to the reduced stand-over provided by the great inclination of the top tube, no climb will be impossible.

THOK Progressive System 2

The new TPS-2 suspension system designed by THOK E-Bikes increases the progressivity of the kinematics and optimises its use in Enduro.

The rear wheel travel is extremely progressive: it absorbs all types of obstacles when riding downhill and ensures maximum traction with climbs. The new full carbon rocker with symmetrical cushioning contributes to zero bending. The TPS-2 features polygonal seat-stay and asymmetrical one-piece chain-stay.

Shimano system – The choice

  • The progression of a motor is how it delivers assistance: Shimano does not have peaks. It feels like a well-trained leg
  • How elastic a motor is is determined by the transition between the push and release phases: with Shimano it is constant and manageable
  • The Q factor (the distance between the cranks) of the EP8 motor is lower: pedalling is more natural
  • The EP8 is one of the lightest and least bulky motors you can find; it has a small and intuitive display, it can be customised and store parameters
  • Shimano has one of the best structured assistance services in the world: always precise and responsive
  • The Shimano closed system (motor, battery, software) guarantees maximum efficiency when it comes to performance and consumption

Performance First - SHIMANO EP8 closed system with 630 Wh battery

Performance is the number one priority in every THOK project. The Gram is equipped with the closed Shimano EP8 system because it guarantees maximum efficiency when it comes to performance and consumption. Tests carried out by the in-house research department have proven this, here are the results:

  • the closed Shimano system, which includes drive unit, battery and software, not only ensures the best possible dialogue between the components but also facilitates troubleshooting thanks to the shared service
  • the 630 Wh capacity battery was found to be the most effective for THOK-style E-Enduro use: flying down breathtaking downhill sections after riding up all kinds of climbs. In fact, it ensures lightness (compared to larger capacity bikes) and better handling (thanks to smaller overall dimensions)
  • in general, the Gram’s frame geometry and kinematics perform best using the complete Shimano EP8 system with 630 Wh battery, especially when it comes to consumption
