Touroll J1 ST 27.5 Inch Trekking E Bike steps into the spotlight as a step through electric commuter bike with a 250W rear hub motor, a 36V 15.6Ah battery rated at 561.6Wh and 27.5 inch wheels aimed at riders who want pedal assist for daily trips and weekend rides.
Motor, Battery and Range
At the core of the Touroll J1 ST is a 250W brushless rear hub motor paired with a 36V electrical system, delivering a quoted maximum torque of 45 Nm for pedal assist on city streets and moderate hills, as documented on one detailed specification review.
A removable 36V 15.6Ah lithium ion battery with a stated power capacity of 561.6Wh sits on the frame and is designed to be taken off the bike for charging, with multiple spec sheets such as this retail listing describing a charging time of about 6-8 hours when charged from empty with the bundled 42V 2A charger.
Manufacturer and retailer descriptions credit the Touroll J1 ST with a claimed maximum range of up to 100 km in pedal assist mode on its 561.6Wh battery, with a typical range band of 50-100 km depending on terrain and support level, a span echoed by the range figures on a European Touroll listing.
Frame, Wheels and Rider Fit
The Touroll J1 ST uses a step through aluminum alloy frame that pairs with 27.5 x 2.1 inch tires, a configuration highlighted on one retailer spec sheet which also lists an 80mm front suspension fork with lockout and mechanical disc brakes front and rear.
Dimension tables such as the one on a geometry focused review describe overall bike dimensions of about 181 cm in length, 68 cm in width and 113 cm in height, with a recommended rider height range of 155-195 cm and a maximum load rating of 120 kg.
The same technical sources quote a net weight around 26.9 kg for the Touroll J1 ST, placing it in a similar weight class to many other trekking style step through e bikes with mid range batteries and 27.5 inch wheels.
Controls, Components and Features
Component wise, the Touroll J1 ST is equipped with a Shimano 7 speed drivetrain, which multiple retailer specifications such as this trekking bike listing confirm, giving riders the familiar combination of pedal assist and gear changes across a moderate range for urban and light touring use.
The bike carries mechanical disc brakes combined with an electronic brake (E brake) cut off system, a pairing described on one retailer spec sheet, aiming to provide consistent stopping power and motor cutoff when the brake levers are engaged.
For rider information, an LCD display sized about 1.8 inches shows assist level, speed and battery status, a detail called out in both retail product listings and independent spec summaries.

Range and Power Compared With Similar E Bikes
In the context of other step through trekking e bikes with 250W hub motors, the Touroll J1 ST’s 561.6Wh battery and claimed 100 km maximum range place it toward the upper end of capacity for an entry to mid level commuter, as evidenced by comparative listings like this product feature that highlight its 36V 15.6Ah pack and 45 Nm torque in comparison to smaller batteries.
Weighing about 26.9 kg and rated for riders and cargo up to 120 kg, the Touroll J1 ST balances battery capacity and frame strength in a way that keeps it competitive with other 27.5 inch trekking e bikes which often carry similar weights but may use smaller 450-500Wh batteries.
Its 25 km/h assist cutoff aligns with regulations in markets where the model is currently documented, and the combination of five pedal assist levels plus a walk mode around 6 km/h, as listed on multiple retailer spec sheets, gives it a typical control profile for a commuter focused hub drive e bike.
Positioning in the Trekking E Bike Segment
Within the broader category of step through trekking and commuter electric bikes, the Touroll J1 ST presents itself as a model that emphasizes range and everyday usability, using a 561.6Wh battery, 27.5 inch wheels and a specified 120 kg max load to support longer routes and mixed use rides.
Riders who want a hub driven e bike with a removable battery, Shimano 7 speed drivetrain and mechanical disc brakes will find that the Touroll J1 ST’s specification sheet aligns closely with mid tier competitors, while its higher capacity battery and 45 Nm torque rating provide a measurable difference in stated range and climbing support within this segment.
