── HIGH-OUTPUT ELECTRIC PERFORMANCE ───────

The 2026 Ultra Bee HP runs a second-generation HairPin-winding permanent-magnet synchronous motor paired with Surron's in-house MTPA/MTPV field-oriented controller. Peak output is 24.5kW in Turbo mode (approximately 32.8 hp) and 21.5kW in Sport mode. Maximum wheel torque reaches 520 N·m (384 ft-lb).

Power is held flat across 2,000–7,000 rpm — full torque whether you're crawling a technical climb or running wide open on a straightaway.

Six riding modes:
- Economy: reduced power for maximum range and beginner-friendly control
- Daily: balanced output for trail riding
- Sport: 21.5kW, performance-focused
- Track: optimized for circuit and MX use
- Reverse: low-speed reverse assist
- Turbo: full 24.5kW peak output

Throttle curve is independently adjustable across three levels.

── 74V 60Ah LITHIUM BATTERY ───────────────

The removable 74V 60Ah battery pack weighs 21.3 kg (47 lb) and delivers 988 W/kg power density and 209 Wh/kg energy density. Cells are sourced from UL-certified suppliers. The pack is certified to UN38.3, MSDS, CE, and RoHS.

Charging from 20% to 80% takes approximately 2.5 hours with the included 1000W smart charger. Estimated range is up to 71 miles at a steady 31 mph under test conditions. Sport and Turbo modes will reduce range. The battery is removable — charge it anywhere.

── SUSPENSION SYSTEM ──────────────────────

Front: Ultra Bee exclusive custom-tuned forks with gold-anodized 7-series aluminum outer tubes. Compression and rebound are independently adjustable. Usable travel: 9.4 inches. Initial stroke is soft, stiffening progressively through mid and late travel — suited to both forest trails and MX tracks.

Rear: INTERSECT TR multi-link rear suspension system with fully adjustable air shock and high-strength alloy spring. Tuned specifically to the Ultra Bee HP's weight distribution to maintain tire contact and grip across varied terrain. Rear shock travel: 3.3 inches.

Ground clearance: 12.4 inches. Handlebar position: 3-level adjustable.

── TRACTION, REGEN & WHEELIE CONTROL ──────

ASR Traction Control (3 levels): Manages rear wheel slip in mud, sand, and loose terrain. Switch between levels on the fly.

SWC Wheelie Control (2 levels, IMU-based):
- N1 Learning Level (15–35°): Smooth, early intervention. Gently limits power near the target angle to help you stabilize.
- N2 Advanced Level (35–60°): Active control at higher angles for experienced riders.
Note: Do not activate SWC during off-road jumps.

Energy Recovery: 5-level coasting regen + 5-level braking regen. Independently adjustable — dial in exactly how much engine braking you want from the throttle and lever.

Auto-Hold: Electronic parking function holds the bike stationary on inclines.

── BRAKING & DRIVETRAIN ───────────────────

The braking system features 90% higher caliper rigidity versus the previous generation, with a light, linear lever feel engineered for confident one-finger control in off-road conditions.

Primary drive uses a carbon-fiber-core belt with ultimate strength increased 60% over the previous design. The pulley surface is coated with tungsten carbide for long-term durability. Secondary drive is chain.
