Road use restricted↓
This model is supplied restricted to 250W and 15.5mph (25km/h), which is why bikes like this are commonly described by retailers as road legal when kept restricted. However, the Department for Transport takes a stricter view of e-bikes that can be configured to provide assistance above the EAPC limits, even if they are supplied restricted and remain in that configuration. We therefore recommend reading our UK E-Bike Road Use Guide before using it on public roads.

checking the handlebars, stem, pedals or wheels,
checking tyre seating and pressures, adjusting
brakes and gears, and checking other safety-critical
components.
Please follow the manufacturer's instructions supplied

✔ Stands out for: Exceptionally large single and dual battery choices, folding storage and 20 × 4-inch Kenda tyres
✔ Better than most for: Riders prioritising substantial battery capacity, useful rack space and comfortable mixed-surface utility
✖ Trade-off: At around 34–36kg, folding does not make it easy to carry upstairs or lift regularly

About the Allegro TDL6125 City Fold Pro E-Bike
The Allegro TDL6125 is a substantial folding utility-style e-bike built around unusually large battery choices. Wide 20 × 4-inch Kenda tyres, front suspension and hydraulic disc brakes give it a planted feel on uneven surfaces and permitted routes. The folding frame helps with storage, although this is emphatically not a lightweight bike to carry.
Battery choice is the standout feature. Single 48V options range from 35Ah to 60Ah, while the dual-battery options combine 35Ah with another 25Ah or 30Ah. That gives approximately 1,680–3,120Wh of nominal battery capacity across the listed variants. More capacity means more stored energy, but range depends on assistance, gradients, weather, speed and load. No single mileage estimate describes every version.
Shimano seven-speed gearing, mudguards and a rear pannier rack add practical utility. At approximately 34–36kg, the TDL6125 is better suited to ground-level storage than regular lifting or stairs. For larger wheels and full suspension in a non-folding frame, compare the Allegro TDL6131. Please consult our UK E-Bike Road Use Guide for legal use requirements.
