Touroll J1 ST 27.5 Inch Trekking E-Bike - 250W Motor And 561.6Wh Battery For Long Rides

Touroll J1 ST 27.5 Inch Trekking E-Bike pairs a 250W rear hub motor with a 561.6Wh removable battery and up to 100 km pedal-assist range. For commuting and light touring, its 27.5 inch wheels and Shimano 7 speed drivetrain matter most.

Touroll J1 ST 27.5 Inch Trekking E-Bike is positioned as a compact electric trekking bike with a 250W rear hub motor, a 561.6Wh removable battery and a claimed pedal-assist range of up to 100 km on a single charge. Riders get 27.5 inch wheels, mechanical disc brakes and a step-through frame designed for everyday use rather than extreme off-road riding.

Motor, Battery And Range

At the heart of the Touroll J1 ST is a 250W brushless rear hub motor rated for 45 N·m of torque and capped at about 25 km/h pedal-assist speed, aligning with European e-bike regulations for pedal-assisted bicycles. Several descriptions of the bike point to this 250W motor and 45 N·m figure as core to its ability to handle urban inclines and moderate touring distances. The powertrain is fed by a 36V lithium-ion battery with a 15.6Ah capacity, yielding a total energy capacity of about 561.6Wh according to detailed spec tables from retailers and reviewers. That battery is described as removable and mounted along the downtube, which allows it to be taken off the bike for charging indoors.

Range claims for the Touroll J1 ST converge on up to about 100 km in pedal-assist mode under favorable conditions, with a more typical range band of 50-100 km depending on assistance level and terrain. Charging time for the 36V 15.6Ah pack is consistently stated around 6-8 hours for a full charge from empty using the supplied charger. The system uses multiple protection circuits to guard against overcharging and overheating, a common feature in modern e-bike battery packs. Combined, the 250W motor output and roughly 561.6Wh battery capacity position the bike as a mid-range commuter and trekking option rather than a high-performance mountain e-bike.

Frame, Wheels And Rider Fit

The Touroll J1 ST uses a step-through trekking frame built around 27.5 inch wheels, which are paired with 2.1 inch wide CST all-terrain tires for a blend of pavement grip and light trail capability. Product listings describe the frame as roughly 27.5 inches with geometry targeted at riders around 5 ft 1 in to 6 ft 5 in, and they cite an adjustable saddle height in the neighborhood of 32.3-40.2 inches combined with a handlebar width of about 680 mm. Total net weight is reported around 26.4-26.9 kg, which reflects the integrated battery, motor and trekking hardware. These values put the bike on the heavier side compared with non-electrified hybrids, but in line with many mid-priced trekking e-bikes.

Suspension duties are handled by a front mechanical shock absorber with about 80 mm of travel and a lockout function, emphasizing comfort over aggressive trail performance. Braking is via mechanical disc brakes front and rear. Drivetrain components center on a Shimano 7 speed derailleur paired with a cassette suitable for general-purpose riding, and the bike incorporates multiple pedal-assist levels tuned between roughly 12 and 25 km/h plus a walk assist function around 6 km/h. Together, these features support a use case of commuting, bike paths and light touring more than steep technical terrain.

Electronics And Controls

On the control side, the Touroll J1 ST is equipped with a compact 1.8 inch LCD display mounted at the handlebars. This display shows speed, battery level and trip distance and allows riders to toggle pedal-assist levels. Walk-assist mode, typically around 6 km/h, can be activated for pushing the bike in tight spaces. While the display is smaller than the large color screens found on some premium e-bikes, its feature set covers key ride metrics and basic configuration.

Lighting and other electronics are typically powered off the main 36V system, although detailed descriptions focus more on range and torque than on accessory outputs. Waterproofing is cited as around IPX4 for the overall assembly, a rating that indicates protection against splashing water from any direction but not full submersion. For everyday commuters, that level of water resistance is designed to handle rain and wet roads but still calls for avoiding deep water crossings.

Positioning Against Other Trekking E-Bikes

In the European home markets where the Touroll J1 ST is widely sold, pricing tends to land around 699-750 EUR at retailers, with some commentary highlighting a manufacturer list price of 1,599 EUR but noting street prices significantly lower. That price band places the bike in a budget to mid-range segment for electric trekking bikes, undercutting many name-brand city e-bikes with similar motor power but more elaborate component sets. Compared with urban commuter e-bikes that may offer hydraulic disc brakes, integrated lights and higher-capacity batteries above 600Wh, the Touroll J1 ST trades some premium components for a lower purchase cost and keeps to a 561.6Wh pack and mechanical disc brakes.

Range and power figures are competitive versus other 250W, 45 N·m hub-motor trekking bikes: claimed ranges up to 100 km on a 36V 15.6Ah battery align with typical expectations in this class, and the torque figure sits near the upper end of basic rear hub systems used for commuting rather than cargo hauling. Riders comparing the J1 ST to non-electric trekking bikes will find weight as the biggest difference, with roughly 26.9 kg far above the 12-15 kg typical of analog hybrid bikes, but they get motorized assistance in exchange.

Manufacturer Presence And Branding

Touroll presents the J1 ST across its branded electric bike collections as a trekking-oriented, step-through frame option alongside other J-series bikes. Official listings emphasize a brushless 250W motor, 561.6Wh battery capacity and up to 100 km maximum assist range, positioning the model for longer rides compared with city-only compact e-bikes. These manufacturer descriptions highlight the removable battery and focus on comfort-oriented geometry, reinforcing the impression of a utility trekking e-bike intended for daily use and recreational touring.

Use Case, Strengths And Limits

For riders in markets where the Touroll J1 ST is sold, the bike fits best as a trekking and commuting platform for paved roads, bike paths and light gravel. The 250W rear hub motor with 45 N·m torque provides enough assistance for rolling hills and loaded panniers without approaching cargo bike levels of hauling power. A 36V 15.6Ah battery with approximately 561.6Wh capacity and an estimated 50-100 km range supports longer daily round trips or weekend rides, as long as pedal-assist levels are used conservatively on tougher segments. Mechanical disc brakes and 27.5 x 2.1 inch tires deliver dependable stopping power and grip for mixed-weather commuting.

Limits arise mainly around weight and component choices. At roughly 26.9 kg net weight, the bike is not easy to carry up multiple flights of stairs or lift frequently, and mechanical disc brakes require more hand effort than hydraulic systems. The 1.8 inch LCD display is functional but basic, and suspension travel around 80 mm at the front underlines comfort rather than aggressive trail capability. Riders seeking higher top-assist speeds than about 25 km/h or stronger climbing power might look to mid-drive systems with higher torque and more refined drivetrains.
