Gram Dream Kit Thok: Full-Carbon frame, Askoll engine and 820Wh battery for EMTB

Thok E-Bikes presents the Gram Dream Kit (DK), a chassis kit designed for those who want to build a MTB from high-performance full-carbon endurocustomizable in graphics, components and driving experience. The package includes a Mullet frame full-carbon developed from scratch, equipped with the Ultra C90a Askoll engine, battery integrated by 820 WHsuspensions Fox Factory KashimaFSA components and Thok brand accessories. The Dream Box is included, which contains the Libellum, a certificate that certifies the uniqueness of the configuration. Proposed at the price of 6,399 eurosthe kit includes shipping and assembly costs. The purchase is made through online configurator, where size, style and aesthetic details are selected, with the possibility of integrating or less additional components. The assembly is entrusted exclusively to Thok or authorized retailers called Dream Builder, also in charge of the approval and recording of the bike.

1 The frame

–

The gram DK frame marks the entry of Thok into the high -performance carbon world. It is an entirely unpublished project, developed without derivations from previous models, which uses the versatility of the fiber to obtain advanced forms and targeted performances. The structure uses unidirectional carbon (UD), which allows you to calibrate the thicknesses selectively: greater in the most stress points, reduced where not necessary. This approach optimizes the mechanical behavior of the frame, while guaranteeing structural resistance, lightness and driving comfort. The high-resistance carbon integration, more flexible, and high module carbon, more rigid, distributed in proportions calibrated on the basis of FEM test (finite element method). Particular attention has been paid to high stress areas, such as the engine area, the steering tube and the rear wagon, which present Specific structural reinforcements. All bearings are installed directly on carbon, without aluminum bushings, a solution that reduces friction and prevents usury phenomena over time. The Technical Package includes FSA TAPERED 1.8 “steering series with sealed bearings, T-Stopper Thok, Thok handlebar attack in CNC processed aluminum, as well as Fsa Pedarty and Crown and Thok Guide. The frame is available in eight colors: Red, Black, Gold, Blue, White, Yellow, Chromed and Holographic.

2 The geometries

–

The possibilities offered by Carbon allowed Thok to develop a geometry without constraints, designed to express maximum pedaling efficiency, traction on descents and stability on the technical traits. The saddle tube with angle of 78 ° Place the biker forward, improving weight balance and push on the pedals, even in steep sections. THE’steering angle open at 64 ° It allows a safe and fluid driving, even in the presence of accidental obstacles or soils. The forms of the frame and its proportions arise from a design process that merges direct experience on trails and attention to technical detail, with the aim of offering a structure suitable for any type of path, without limits for those who pedal.

3 The engine

–

The GRAM engine system is entrusted to the Power Unit Askoll Ultra C90aexpression of the competence gained by Askoll in the electric propulsion sector. The engine provides a peak power of 1,200 watts and a maximum torque of 90 nmoptimized for ideal operation in the range between 60 and 80 pedaling per minute. Pedal assistance is adjustable on five levels, offering precise modulation of the support based on the type of use and the soil faced. The battery integrated by 820 WHhoused inside the frame, guarantees high autonomy, making the Gram suitable for longer outings.

4 The suspensions

–

Gram suspensions are based on the new scheme TPS-2 (Thok Progressive System 2)developed specifically to maximize mechanical efficiency in the enduro field. There rear suspension Progressive absorbs impacts with descent efficacy and maintains excellent uphill traction. The new rocker entirely in carbon, equipped with symmetrical bearboard, cancels the unwanted decreases of the system. The rear wagon adopts a configuration with Seat-Stay with a polygonal section e Chain Stay Monobloc asymmetrical, solutions that guarantee rigidity and precision in the transmission of forces. The suspension sector is completed with a fork Fox 38 Float Factory Kashima 180 mm excursion and a Fox Float X2 Factory Kashima shock absorberboth developed to offer sensitivity, support and control over the most demanding paths.

5 Assembly

–

The assembly of the GRAM DK is entrusted to Thok or authorized dealers recognized as Dream Builder, the only ones authorized to perform the assembly, recording and approval of the bike. Manoding costs for assembly are entirely borne by Thok E-Bikes. The customer has the possibility to integrate components already in his possession or to complete the set -up by choosing from the options available in the configurator. The Dream Builder It provides technical advice and guarantees that the assembly takes place according to the specifications of the parent company. At the time of retreat, it is necessary to check that the bike was recorded on the THOK website for activating the warranty. Delivery and assembly end with the Dream Box, which contains the Libellumthe THOK certificate attest to the uniqueness of the configured Gram DK.
