Overview
The Trek Slash+ is Trek’s gravity-focused electric mountain bike, combining the analog Slash Gen 6’s proven high-pivot suspension design with the TQ HPR60 motor system. With 170mm of front and rear travel delivered through the same high-pivot, idler-pulley layout as the analog Slash, the Slash+ is built for riders who want motor-assisted access to the most demanding terrain. The high-pivot design provides exceptional bump absorption at speed — a trait that becomes even more valuable with the extra weight of a motor system.

The Slash+ runs a fixed mullet wheel configuration (29″ front, 27.5″ rear) across all sizes — unlike the analog Slash, there is no option to convert wheel sizes. Geometry is aggressive with a 63.4° head angle using the neutral headset cups, adjustable by ±1.0° with optional angle-adjust cups for three total positions. The TQ HPR60 motor produces 60Nm of torque and 350W peak power with a 580Wh battery, making this a relatively lightweight eMTB compared to full-power alternatives. Reach ranges from approximately 435mm (S) to 510mm (XL) with size-specific chainstays from 434mm to 445mm.

Geometry Analysis
The Slash+ shares the analog Slash’s uncompromisingly aggressive geometry. The 63.4° head angle (neutral cups) is among the slackest in the eMTB enduro class, and the ±1.0° adjustment range with aftermarket headset cups means riders can go as slack as 62.4° for pure gravity riding or as steep as 64.4° for more balanced trail handling. Size-specific chainstays (434-445mm) maintain proportional handling, and the consistent 27mm BB drop and 350mm BB height keep the center of gravity low. The high-pivot suspension layout — identical to the analog Slash — moves the rear axle rearward on impact, which is particularly valuable on a heavier eMTB where maintaining rear wheel traction through chunk is critical.
Ride Characteristics
The Slash+ is a gravity-focused eMTB that happens to have a motor, rather than an eMTB that happens to descend well. The high-pivot suspension eats rough terrain with the same authority as the analog Slash, and the extra weight from the motor actually helps plant the bike through rough sections. The TQ HPR60 motor provides enough assistance to get you to the top without being as heavy or powerful as a full Bosch CX setup — it’s a lighter, more natural-feeling system that rewards riders who still want to pedal. On descents, the Slash+ is phenomenal: the mullet wheel setup, slack geometry, and 170mm of travel combine to create a bike that feels composed at speeds that would overwhelm most eMTBs. Where it shows limits compared to the Rail+ is raw motor power and battery range — the 60Nm motor and 580Wh battery mean you’ll run out of juice faster on big vertical days.

What’s New vs Previous Generation
The Slash+ launched in 2025 as Trek’s first electric version of the high-pivot Slash platform. Rather than the full-power Bosch motor used in the Rail+, Trek chose the lighter TQ HPR60 system — a deliberate decision to keep the weight closer to an analog bike and preserve the Slash’s renowned descending character. The carbon frame was designed from the ground up to integrate the TQ motor and battery while maintaining the high-pivot suspension geometry. The fixed mullet wheel configuration (no conversion option) reflects Trek’s commitment to optimizing the Slash+ for its intended purpose: gravity-focused riding with motor assistance.
Who Should Consider This Bike
The Slash+ is for riders who love the Slash’s descending prowess but want motor assistance for the climbs. It’s ideal for enduro riders who want to log more laps, shuttle-style access without a truck, or the ability to ride longer days on demanding terrain. The lighter TQ motor makes it feel more natural than full-power eMTBs — closer to an analog bike on the downs. Riders who need maximum motor power and range should consider the Rail+ instead. Those who want a more balanced trail eMTB should look at the Fuel+ EX.
Comparable Models
The Slash+ competes with the Specialized Turbo Kenevo SL, Santa Cruz Bullit SL, Orbea Wild SL, and Canyon Torque:ON. The Slash+ is unique in combining a high-pivot suspension with a lightweight motor — most competitors use conventional suspension designs. The Kenevo SL is the closest competitor with its lightweight motor and gravity focus. The Canyon Torque:ON uses a full-power motor in a gravity chassis. The Slash+’s TQ HPR60 motor is shared with the Fuel+ lineup, offering a cohesive ecosystem.

Frequently Asked Questions
What motor does the Trek Slash+ use?
The Slash+ uses the TQ HPR60 motor, which produces 60Nm of torque and 350W peak power while weighing just 1.92kg. It’s paired with a 580Wh integrated battery. This is a lightweight motor system — less powerful than the Bosch CX in the Rail+ but significantly lighter.
Can the Trek Slash+ run full 29″ wheels?
No. Unlike the analog Slash Gen 6 which offers convertible wheel sizes, the Slash+ has a fixed mullet configuration (29″ front, 27.5″ rear) across all sizes. The frame and suspension were optimized specifically for this wheel configuration.
What is the difference between the Trek Slash+ and Trek Rail+?
The Slash+ uses the lighter TQ HPR60 motor (60Nm, 580Wh) with 170mm travel and high-pivot suspension — it’s lighter and more descending-focused. The Rail+ uses the Bosch CX motor (85Nm, 800Wh) with 160mm travel and conventional suspension — it’s heavier but more powerful with significantly more battery range.
How much does the Trek Slash+ weigh?
The Slash+ weighs approximately 42-45 lbs (19-20.5 kg) depending on the build and size. This is notably lighter than full-power eMTBs like the Rail+ (50-54 lbs) thanks to the TQ motor system.
Does the Trek Slash+ have adjustable geometry?
The Slash+ comes with a neutral headset cup position giving a 63.4° head angle. Trek offers aftermarket angle-adjust headset cups that allow ±1.0° of adjustment, providing three possible head angle positions: 62.4°, 63.4°, or 64.4°.
