The JackRabbit MG Doble isn’t your typical electric bike. It’s a compact, powerful machine designed for utility, not fitness. Think a scaled-down motorcycle with bicycle dimensions. The model tested, sporting a candy-apple red frame and chopper-style handlebars, immediately evokes a sense of raw, unrefined fun. But beneath the playful aesthetics lies a vehicle that blurs the line between recreational toy and practical transport.
What It Is (and Isn’t)
JackRabbit intentionally avoids neat categorization. CEO Jason Kenagy positions the Doble as an alternative to cars, not bicycles. This is key: the Doble isn’t about leisurely rides. It’s about getting from point A to B, efficiently, even if that means bypassing bike paths.
The 52-pound frame can haul up to 325 pounds—enough for two adults or a load of cargo. Unlike traditional e-bikes, there are no pedals, no gears, and no pretense of physical exertion. This simplicity is both its strength and its weakness.
Power and Performance
The Doble packs a 749-watt motor and dual 360-Wh batteries (combined 720-Wh), delivering roughly 48 miles of range. Three modes—Eco, Mid, and High—manage power output, with High capping at 20 mph. An “off-road” mode (for riders 18+) unlocks unrestricted speed.
The mixed-wheel design (20-inch rear, 24-inch front) enhances stability over rough terrain. While torque figures remain undisclosed, Kenagy confirms the Doble outmatches JackRabbit’s XG Pro model in climbing ability.
Designed for Utility
Instead of pedals, the Doble features foldable foot platforms. Rear passengers get forged aluminum pegs. Both footrests, along with the handlebars, fold flat for storage or transport.
JackRabbit’s accessory ecosystem further enhances utility. Braze-ons accommodate rear baskets, panniers, and even trailer hitches. Add-ons like a travel battery (extra 10 miles range) and a lift kit (for taller riders) expand the Doble’s versatility.
The Ride Experience
The Doble excels at urban tasks. Hauling cargo (compost, groceries, surfboards) is effortless. The bike handles potholes and rough roads with ease. However, its lack of pedal assist and high power output demand caution.
On city streets, the Doble behaves more like a scooter than a bicycle. The twist-grip throttle is sensitive, requiring careful control. Steep hills demand full throttle, but the bike’s speed can be surprisingly slow (around 12.5 mph uphill).
Two-person riding requires balance and coordination. Unexpected wheelies are possible, especially with sudden acceleration.
The Trade-Offs
The JackRabbit MG Doble is a unique vehicle with clear strengths. It’s powerful, compact, and highly customizable. But it’s not for everyone.
Accessories add to the cost. The lack of pedaling means zero exercise benefit. And legality is murky: many cities restrict motorized vehicles from bike paths.
The Doble isn’t about recreation; it’s about function. It’s a tool for those who prioritize utility over fitness, and who are willing to navigate the legal gray areas that come with it.
In short, the MG Doble is a thrilling, if slightly reckless, urban workhorse
