The Trek Checkpoint+ SL is Trek’s electric gravel bike. It has a carbon frame, the 60 Nm TQ HPR60 motor, a 360Wh battery and room for 50mm tires. There are three builds. The SL 5 is $5,599.99 with Shimano GRX. The SL 6 AXS is $6,599.99 with wireless SRAM shifting. The SL 7 AXS is $7,999.99 and adds a 40mm suspension fork and carbon wheels. All three weigh about 30 to 31 lb. I haven’t ridden any of them. Below I compare them with the Trek FX+ 7S and with the Velotric T1 ST, which I filmed. Everything here comes from Trek’s product pages, checked on Oct 28, 2026 and linked at the bottom.
Motor, battery and class
The TQ-HPR60 is rated at 60 Nm, with 250W continuous and 350W peak. It has three assist modes, and Trek calls it compact and quiet. It’s a Class 3 bike, so assist runs to 28 mph, and Trek doesn’t list a throttle. Some trails and paths are closed to Class 3 bikes, so check our e-bike laws hub and the Class 2 vs Class 3 guide first.
The battery is a TQ 360Wh pack, and the bikes come with a TQ 4A charger. Trek claims up to 50 miles in Eco mode. An optional 160Wh Range Extender fits in a bottle cage, and Trek says it adds 44% more range. The Trek Central app shows your range and handles ride tracking, motor tuning and navigation.
Built for long gravel days
The 500 Series OCLV Carbon frame uses Trek’s IsoSpeed and Gravel Endurance geometry. Trek describes the geometry as more relaxed and upright. The bikes come with Bontrager Girona Pro 700x42mm tubeless ready tires, and Trek says the frame fits tires up to 50mm wide as measured.
There are mounts for front and rear racks, fenders, and Trek’s Adventure Frame Bag and Triangle Bag. The rigid carbon fork on the SL 5 and SL 6 has triple rack mounts. Trek says the frame works with a suspension fork of up to 40mm and a dropper post, but the suspension fork isn’t offered on size XS.
The weight limit is 275 lb total, including the bike. None of the builds come with pedals.
SL 5, SL 6 or SL 7

How it compares
Against the Trek FX+ 7S: it’s a flat bar hybrid with a 50 Nm TQ-HPR50, the same 360Wh battery size and 28 mph assist. It weighs about 41 lb with a rack and fender, and it was $3,199.93 on closeout on Oct 28, 2026. The Checkpoint+ SL is about 10 lb lighter as listed, has more torque, drop bars and much wider tires, and costs at least $2,400 more.
Against the Velotric T1 ST, which I filmed: it weighs 36 lb and has a 350W rear hub, a 353Wh battery and Class 1 assist to 20 mph. Its battery is about the same size as the Checkpoint’s, but the Checkpoint+ SL is built for gravel, with a mid drive motor, 42mm tires and mounts for bags and racks.
Trek’s Domane+ ALR uses the same motor and battery on an aluminum road frame. It clears 40mm tires and costs about $5,000. If most of your riding is on pavement, look at the Domane+. If you ride a lot of dirt, the Checkpoint+ has more tire room and more mounts.
