  • Must have pedals installed and pedal assistance limited to 15.5mph to maintain EAPC status.

1920s Board-Tracker Heritage Meets Modern Electric Mobility

Designed with bold retro nostalgia, the Michael Blast Outsider draws immediate inspiration from the dangerous board-track racing motorcycles of the 1910s and 1920s. Its distinctive drop-loop frame, central petrol tank enclosure, wide swept-back cruiser handlebars, and low-slung stance give it an unmistakable profile.

Unlike minimalist modern commuter bikes, the Outsider is built as a lifestyle showpiece. Every detail—from the vintage font decals to the leatherette grips, inverted front suspension fork, and large retro headlight—is tuned for vintage motorcycle lovers who want zero-emission city travel.

Long Wheelbase and Fat Tyres: Handling City Corners and Wet Roads

With a generous wheelbase and a kerb weight of roughly 28kg, the Outsider feels exceptionally stable and planted at speed. The 20x4.0 Innova fat tyres provide substantial air cushioning, soaking up potholes, cobblestones, and cracked urban tarmac with ease.

However, the relaxed head-tube angle and long frame mean the turning circle is significantly wider than that of a standard hybrid. Navigating tight bike shed doorways or weaving through dense stationary traffic requires deliberate planning.

In wet conditions, keep tyre pressures between 18 and 22 PSI to maximise the rubber contact patch on slick tarmac and damp road paint.

Central Tank Battery Enclosure and Hydraulic Braking Safety

The Outsider's 48V battery pack is concealed within the aerodynamic teardrop top-tube tank. Equipped with high-density Samsung lithium-ion cells (typically 14Ah or 672Wh), the battery delivers an authentic 30 to 45 miles of real-world pedal assist in typical UK weather.

Stopping a 28kg vintage e-bike requires serious hydraulic braking power. The Outsider features dual-piston hydraulic disc brakes with 180mm front and rear rotors. The hydraulic fluid provides smooth, modular lever feel, eliminating the cable stretch and spongey brake response common on cheaper mechanical setups.

What to Check Before Purchasing a Used or New Michael Blast Outsider

1. Inspect the motor hub engraving: verify that it clearly specifies 250W and not 500W or 750W.

2. Check throttle behaviour: ensure that any fitted throttle operates only as a 3.7mph walk-assist or is disconnected.

3. Test battery lock: ensure the key mechanism securely locks the battery into the central tank frame.

4. Confirm charger specifications: check that the charger bears UKCA/CE safety marks with appropriate fuse protection.
