A comprehensive breakdown of our two frame platforms covering head tube angles, reach stacks, chainstay lengths, and BB drop across all sizes. Includes K-Volve kinematics anti-squat data, flip-chip travel configurations, and the S-Volve RA headset reach-adjust system.

Height is the worst single predictor of fit, and everyone in the industry knows it. This white paper walks through manufacturer height charts, stack and reach, road-derived fit systems, and rider-first frame platforms, then explains the TGI method: TGI Reach and TGI Rise Angle, the two numbers we use, and the four field tests we run before we trust any number.

An industry outlook synthesizing 2026 market, regulatory, and behavioral data. Covers the rise of 'light-full-power' motors, the US/EU regulatory split, eMTB ownership demographics, mid-drive market share by torque class, and the disconnect between the power buyers request at purchase and the power they actually use on the trail.

Benchmarks twelve mid-drive motors across weight, battery capacity, support ratio, torque, peak power, and noise. Covers EU pedelec and US Class 1 regulatory compliance in detail. Essential reading for anyone comparing mid-drive systems before purchasing.

Power delivery, efficiency, pedal feel, and app control across four drive units that answer the same question differently. Covers reaction speed, overrun behavior, Q-factor, thermal management, battery strategy, and the full depth of each rider app. Based on manufacturer ratings with TGI Cycling's assessment of real-world behavior.

A practical, evidence-based reference for setting up modern trail and enduro suspension. Covers the universal sag, rebound, compression, and spring-curve method, brand-specific procedures for seven suspension houses, cross-brand comparison charts, and a dedicated section on the DIRTLAB CP (Concentric Pivot) platform including the 85 kg DVO Topaz T3 reference tune.

Synthesizes peer-reviewed research on exercise intensity, cardiorespiratory fitness, structured training, injury risk, and rehabilitation. Key findings: eMTB riding retains ~94% of analog average heart rate (BYU pilot study), produces comparable VO₂peak gains in controlled trials (Basel RCT), and serves as an adjustable load dial for physical therapy and return-from-injury protocols.

An evidence-based analysis of Q-factor (the horizontal distance between crank arms) and its biomechanical consequences for the hip, knee, and ankle through every pedal stroke. Covers how mid-drive eMTB motors push cranks wider than analog bikes, what the controlled literature says about stance width and knee load distribution, and practical implications for bike fit and motor selection.

An evidence-based guide debunking the efficiency myth and clarifying the real trade-offs: foot security, safety, knee health, and skill development. Covers the physiology of float in clipless systems, the unconstrained freedom of flat platforms, and a practical decision framework matched to rider type, terrain, and injury history.
