What works

  • KTM's electric 50cc-class MX bike: 5 kW peak, a water-cooled motor, and six selectable power modes that scale from first-timer to competitive Junior E-Motocross
  • Backed by KTM's large US dealer network for parts, service, and warranty support - a real edge over import youth e-bikes
  • Swappable 907 Wh KTM PowerPack and an adjustable 24.9-26.8 in seat let one bike grow with the rider

Trade-offs

  • $5,799 before a $425 freight charge and dealer setup - premium money for a youth bike
  • Mechanically identical to the Husqvarna EE 5 and GasGas MC-E 5; you are largely paying for KTM badging over the $5,449 GasGas
  • No published top speed or mileage range, no display or app, and off-road only - runtime is measured in motos, not miles

Claim vs. real-world check

Identical platform (SX-E 5 = EE 5 = MC-E 5)

Rated: Marketed as three separate brand models

Observed: All three share the 48V/21Ah/907Wh KTM PowerPack, the 2 kW rated / 5 kW peak water-cooled motor, six ride modes, a 40.5 kg chassis, WP 205/193 mm suspension, 12/10 in wheels, 160 mm discs, and 259 mm ground clearance. The only differences are bodywork, graphics, brand/dealer, and price: GasGas $5,449, KTM $5,799, Husqvarna $5,849, each plus $425 freight. KTM's own page omits weight, battery Ah, and motor torque; those are taken from the identical EE 5 / MC-E 5 pages.

Cross-shoppers should choose on price and nearest dealer, not spec. Verified against all three official 2027 model pages on 2026-07-24.

Top speed and range

Rated: Not published

Observed: KTM publishes no top speed and no mileage range for the SX-E 5; runtime is quoted as ride time by power mode, not miles. It is a mode-limited youth bike, far below adult-trail-bike speed.

top_speed_mph and range_mi_claimed are null rather than a guessed figure.
