The Trek Charter+ makes the most sense when your day is full to the brim. It’s the e-Bike I’d look at when one ride turns into three: work, groceries, a stop across town, then the hills back home. That’s the Charter+ vibe: comfortable, useful, and easy to ride.
Trek already makes lighter, simpler e-Bikes. The Charter+ has a different job. The Bosch motor, clean frame, lights, rack, fenders, and upright position all point in the same direction: to make everyday riding feel fun, relaxing, and worth repeating.
Below, I’ll look at what the Trek Charter+ is, how the 4S and 5S compare, what the bike should feel like on everyday rides, and who I’d recommend it to. I’ll also cover what to check when shopping for a certified pre-owned Trek city e-Bike on Upway.

What is the Trek Charter+?
The Trek Charter+ is an electric city bike built around comfort, utility, and Bosch mid-drive support. It’s not an e-MTB, a cargo bike, or a stripped-down commuter. Think upright city riding with enough speed and built-in equipment to handle lots of riding during the week.
The frame is Premium Alpha Platinum Aluminum, and the build is aimed at real daily use: front suspension, a suspension seatpost, adjustable stem, full fenders, chainguard, hydraulic disc brakes, wide fast-rolling tires, integrated running lights, a top-eject removable battery, a 60 lb-rated MIK HD rear rack, and compatibility with the Bosch eBike Flow app.
That’s a lot of commuter equipment, but it has a purpose. This bike is great for carrying stuff, riding after dark, locking up, charging, climbing hills, and staying comfortable on rough pavement.
Trek Charter+ 4S vs. Trek Charter+ 5S
The 4S and 5S differ in battery capacity, drivetrain feel, and how far you can ride between charges.
| Model | Best for | Key difference |
|---|---|---|
| Trek Charter+ 4S | Fast city rides and shorter commutes | 540Wh battery, up to 45 miles of range |
| Trek Charter+ 5S | Longer commutes and heavier daily use | 800Wh battery, up to 68 miles of range |
| Charter+ 5S Lowstep | Easier mounting and less charging | Lowstep frame, 800Wh battery, Auto Shift |
| Charter+ 4S Lowstep | Speed with easier access | Lowstep frame, 540Wh battery, Class 3 assist |
The Charter+ 4S is the one I’d pick if your routine is pretty dialed: commute, errands, bike paths, town riding, and maybe some hills. Trek lists the Charter+ 4S with a Bosch Performance Line Sport motor, up to 85 Nm of torque, Class 3 assist up to 28 mph, a 540Wh battery, up to 45 miles of range, and a 5-hour full charge. The 540Wh battery gives you a useful range without raising the price to the 5S level.
The Charter+ 5S is for the rider whose day keeps expanding. Maybe you commute farther or carry more. Maybe you don’t want to think about charging every other ride. The Charter+ 5S uses the same Bosch Performance Line Sport motor and 28 mph assist, but gets an 800Wh battery, up to 68 miles of listed range, and a 7-hour full charge. The 800Wh battery is the big upgrade, and Shimano Auto Shift fits the bike's easygoing commuter personality.
Personally, I’d pay extra for the 5S if I knew I’d use the range. If most rides are short, the 4S is the smarter buy. But if the bike is replacing car trips several days a week, the bigger battery and Auto Shift feel less like luxuries and more like the point of the bike.
What does the Charter+ feel like to ride?
The Charter+ wants to settle into a steady city pace and stay there. It’s best on rides where you’re not trying to suffer or sprint. You’re rolling through neighborhoods, crossing town, doing errands, taking the long way home because the bike makes riding easy and fun! It’s the one I’d pick if I wanted to arrive without feeling sweaty.
The upright position is a big part of that. You’re not hunched over as you would be on a road bike, and you’re not stretched out as you might be on a sportier hybrid. The adjustable stem helps dial in the handlebar position, which is great if you’re sharing the bike, coming back to riding after time away, or trying to reduce pressure on your hands and back.
The Bosch Performance Line Sport motor fits the Charter+ well. With up to 85 Nm of torque and assist up to 28 mph, it has the numbers for a serious Class 3 city e-Bike, but speed isn’t the whole story. The real value is getting across town without feeling challenged by every hill, stop-and-go section, and rough sections of pavement.
The front suspension and suspension seatpost help, but just for daily comfort. This isn’t a trail bike. Those parts are there for rough pavement, brick paths, bumpy sections, and the kind of city streets that make a rigid bike feel harsh.
Who is the Trek Charter+ for?
The Charter+ is for the rider who wants the bike to be part of their routine, not just something that comes out once in a while. It works for riders who want to ride more often but don’t want every ride to feel like a workout.
I’d recommend the Charter+ for:
- Daily commuters who want comfort and speed
- Riders with longer city routes
- People replacing short car trips
- Errand riders who need a real rack, lights, and fenders
- Riders who want an upright position
- People who prefer Bosch mid-drive systems
- Anyone who wants a Trek commuter with dealer support
Where I’d hesitate is price. The Charter+ 4S starts around $4,000, while the Charter+ 5S is around $4,500. That is real money for a city e-Bike, even one with Bosch power and strong daily-use details. I’d also hesitate if you want a lighter, sportier ride. The Charter+ may feel like too much bike if you only want short bike-path loops or occasional weekend rides.
Trek Charter+ features and accessories
The great stuff isn’t buried in the specs. It’s the everyday equipment: battery access, lights, rack, brakes, app features, and comfort parts. The top-eject battery is one of the better details. If you store the bike in a garage, apartment, office, or a tight bike room, removing the battery can get tricky. Trek says the Charter+ battery comes out from the top of the downtube and has a magnetic, color-matched cover with an integrated strap for charging, storage, and carrying.
The Bosch eBike Flow app is more useful here than it would be on a casual path bike. Trek lists digital locking, theft alerts, customizable ride modes, and navigation through the app. On a city e-Bike that may sit outside a grocery store, coffee shop, or office, that’s great for peace of mind.
The rack is also great. Trek lists a 60 lb-rated MIK HD rear rack, which makes the Charter+ more realistic for groceries, work bags, baskets, or a compatible child seat. Full fenders and a chainguard help keep you and your gear cleaner, which matters if you’re riding to work or running errands in normal clothes.
