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

Touroll J1 ST 27.5 Trekking Electric Bike targets riders who want pedal assist on paved roads and light trails without giving up a familiar bicycle feel. The step-through frame pairs a 250W rear hub motor with a 561.6Wh removable battery, 27.5-inch wheels, and Shimano 7-speed gearing for controlled support up to 25 km/h.

Powertrain, Battery And Assisted Range

At the center of the Touroll J1 ST is a 36V brushless rear hub motor rated at 250W, delivering up to 45 N.M of torque for pedal assist in line with common pedelec limits around 25 km/h in assist mode.Touroll J1 ST powertrain data Energy comes from a 36V lithium-ion battery with a 15.6Ah capacity and a stated power capacity of 561.6Wh, mounted along the downtube and designed to be removable for charging and storage.Battery specifications on Touroll site

The manufacturer lists a maximum assisted range of up to 100 km on a full charge in pedal-assist mode under favorable conditions, with a more typical band described between roughly 50 and 100 km depending on assistance level and terrain.Range figures for J1 ST Charging time for the 36V 15.6Ah pack is consistently stated around 6-8 hours for a full cycle from empty using the supplied charger.Charging time and capacity details For riders planning longer days, that combination of battery capacity and range means a work commute and a weekend ride can often fit into one charge in assist modes that stay below the maximum support setting.

Frame, Wheels And Rider Fit

The Touroll J1 ST uses a step-through frame aimed at making mounting and dismounting easier, particularly when carrying bags or wearing everyday clothes.Step-through frame description Wheel size is listed at 27.5 inches with 27.5 x 2.1 inch tires, balancing rolling efficiency on pavement with enough tire volume for light gravel and uneven urban surfaces.Wheel and tire specifications A front suspension fork with approximately 80 mm of travel is cited, with a lockout function to stiffen the fork when riding on smoother roads or climbing where energy transfer matters more than comfort.Suspension travel and lockout details

Spec tables give a net weight of about 26.9 kg for the J1 ST, a figure typical for trekking-oriented e-bikes with this size battery and wheel format.Weight listing for J1 ST Recommended rider height spans roughly 155-195 cm, and maximum rider weight is specified at 120 kg on some listings, indicating that the frame and components are built to handle heavier loads than a non-assisted city bike.Rider height and load guidance Those numbers place the J1 ST squarely in the trekking e-bike segment rather than in a lighter hybrid category.

Drivetrain, Brakes And Controls

The Touroll J1 ST relies on a Shimano 7-speed derailleur setup to manage mechanical gearing, paired with a single chainring up front for straightforward shifting on commutes and leisure rides.Shimano 7-speed drivetrain information The motor offers five assist levels plus a walk mode according to detailed retailer and brand descriptions, allowing riders to tailor support to gradient and desired effort.Assist level and walk mode listing A 1.8-inch LCD sits on the handlebar to show speed, assist level, battery state, and other basic ride data, aligning the bike with contemporary expectations for real-time feedback on e-bikes.LCD display specifications

Braking duties fall to mechanical disc brakes with an additional electronic brake function that cuts motor power when the brake levers are engaged.Disc brake and e-brake description The braking setup is listed alongside an IPX4 water-resistance rating for the electrical system, intended to cover splashes and light rain without encouraging submersion.Water resistance and braking system Integrated lighting, typically including a front LED headlight, is part of the equipment list to meet road-traffic regulations in the markets where the J1 ST is sold.Lighting and regulatory equipment data

Market Positioning And Pricing Context

Retail and comparison listings in Europe place the Touroll J1 ST trekking e-bike in the mid-range segment by price, with figures such as 769 EUR and 749 EUR cited on specialist sites.Price band context in EUR On the Touroll trekking e-bike collection page the J1 ST appears alongside other trekking models, with pricing expressed in euros, underscoring that current published prices focus on European markets rather than a US MSRP.Trekking e-bike collection listing That puts the model roughly in line with many commuter-focused e-bikes that blend modest motor power, mid-capacity batteries and entry-to-mid level components instead of premium drivetrains or high-torque motors.

As a trekking electric bike with a 561.6Wh battery, 250W motor and 27.5-inch wheels, the J1 ST aligns with comparable European pedelecs that typically advertise ranges around 80-120 km and similar charging times of about 6-8 hours from standard wall chargers.Comparative range and positioning Although US-specific distribution and pricing are not detailed on the Touroll brand pages, the technical makeup situates the bike as an option for riders who value range and practicality over very high top speeds or high-torque hill climbing beyond the 45 N.M figure.

Comparison With Segment Alternatives

Within the trekking and commuter e-bike category, a 250W motor and 561.6Wh battery give the Touroll J1 ST a capacity and power pairing similar to many mid-range models that advertise around 500-600Wh of battery energy.Battery energy listing Compared with basic city e-bikes that might use around 400Wh, the J1 ST’s 561.6Wh pack supports the higher end of the often-cited 50-100 km range band, while still staying under the much heavier systems that push toward 700-900Wh and add notable weight. With a net bike weight around 26.9 kg, the J1 ST does not compete with lightweight 20 kg commuter e-bikes but remains manageable for storage and handling compared with cargo-focused machines that can exceed 30 kg.Net weight as comparison point

Torque output of 45 N.M sits below high-torque mid-drive systems that may claim 60-85 N.M but above very low-power hub systems that stay closer to 35 N.M, placing the J1 ST as a moderate climber rather than a hill-specialist.Torque figure for J1 ST The IPX4 water-resistance rating matches many commuting e-bikes designed for everyday weather rather than full off-road use, and the mechanical discs combined with e-brake functions follow a common pattern for cost-conscious but functional stopping setups.Water resistance and braking comparison For riders weighing range and comfort features against purchase price, the J1 ST’s battery size and suspension travel position it as a practical trekking option in the European mid-range segment.

Use Case, Strengths And Limits

The Touroll J1 ST is aimed at commuters and recreational riders who favor paved routes, light gravel, and bike paths over steep technical trails, making its 27.5 x 2.1 inch tires and 80 mm front suspension an appropriate pairing for mixed-surface urban and suburban use.Intended use and surface guidance A claimed maximum assisted range of up to 100 km and charging time of 6-8 hours support planning for round-trip commutes, weekend rides and occasional longer excursions, as long as the rider stays mindful of assist levels and terrain.Range and charge-time planning data The step-through frame and recommended rider height band from about 155 to 195 cm widen accessibility for different users, including those who prefer easier mounting.Rider sizing and accessibility figures

Limits show up in the fixed 25 km/h assisted cut-off speed typical of pedelecs in many markets and in the mechanical disc-brake setup, which lacks the feel and low-maintenance operation of hydraulic systems common on higher-priced trekking bikes.Assisted speed and brake type listing For riders in hilly regions or those wanting speeds beyond 25 km/h under assist, other segment models with more torque or different regulatory categories may fit better. For those primarily intending commuting and relaxed trekking within this speed band, the J1 ST offers a balanced mix of 561.6Wh battery capacity, 250W motor power, 80 mm suspension travel, and 27.5-inch wheels in a step-through package.
