About The Trek Charter+ 4S Lowstep E-Bike
The Trek Charter+ 4S is a full-featured electric city bike built around the Bosch Performance Line Sport Smart System, delivering 85Nm of torque and assist up to 28 mph. It combines a Premium Alpha Platinum Aluminum frame with SR Suntour coil front suspension, a top-eject 540Wh PowerTube battery, and a Shimano CUES 9-speed drivetrain — a complete package for riders who want range, reliability, and upright comfort on urban routes.
The Bosch eBike Flow app connects digital locking, theft alerts, navigation, and custom assist modes to your phone. A color-matched magnetic battery cover allows tool-free removal for charging. Trek LED lighting (400 lumen low / 800 lumen high beam), an integrated MIK HD rear rack rated to 60 lbs, and a suspension seatpost round out a bike that is ready to carry cargo, passengers, and the unexpected. The Shimano LINKGLIDE 11-46 cassette is designed for long-term durability under daily use and Shimano MT200 hydraulic disc brakes with 180mm rotors provide consistent stopping in all conditions.
Who It's For
- Commuters who want a premium city e-bike with meaningful speed (28 mph Class 3) and long range
- Riders who want Bosch Smart System connectivity — navigation, digital lock, activity tracking
- Those carrying cargo or panniers regularly — the MIK HD rack handles up to 60 lbs
- Riders who want built-in security and app integration without adding accessories
What to Look For
- Lowstep vs. standard frame: The Charter+ 4S Lowstep uses the same motor, battery, and drivetrain as the standard frame — the choice is about frame entry height and preferred handlebar sweep
- Battery capacity: The 540Wh PowerTube supports up to 45 miles depending on assist level and terrain
- Bosch Smart System: Current-generation Bosch platform with ongoing app updates and future accessory compatibility
Key Features
Frame — Premium Alpha Platinum Aluminum: Integrated cockpit routing, top-load battery housing, adjustable bolt-on dropout, integrated rack and fender mounts. Easy-on lowstep geometry with adjustable stem for personalized riding position.
Motor/Battery — Bosch Performance Line Sport, Smart System: 85Nm, 750W, assist to 28 mph. Bosch PowerTube 540Wh top-eject battery with color-matched lockable cover. 45-mile range estimate in moderate assist conditions.
Drivetrain — Shimano CUES 9-speed: Shimano U4000 shifter and rear derailleur, LINKGLIDE LG300 11-46 cassette, and LG500 chain. Designed for durability under daily commuting use.

Rider Intent Summary
- Biggest strengths: Bosch Smart System connectivity with digital lock and navigation; 28 mph Class 3 speed; MIK HD rack; lowstep frame for easy mounting
- Tradeoffs: 540Wh battery is capable but not the highest capacity in the class; coil front fork is comfortable but not highly adjustable
- What makes it different: The lowstep frame gives riders who want easy mount/dismount access to the same high-spec Bosch Smart System as the standard Charter+ 4S
Victory's Take
At Victory Bicycle Studio, we see the Charter+ 4S as a strong choice for riders who want a city bike that does the commute job well and adds meaningful connectivity through the Bosch Smart System — it earns the premium price more through the integrated security and app features than through raw hardware alone.

Frequently Asked Questions
How is the bike packaged and how long does delivery take?
All bikes are securely packaged to ensure that damage doesn't occur during shipping. All parts of the bike are padded and if needed, zip tied to minimize or eliminate movement inside the box. Once a bike is handed to the shipping company (usually Fedex or UPS), depending on your location, delivery will range from 1 day to 8 days. If you do choose the option for Professional Assembly or White Glove Delivery, this can add anywhere from 2 days to 5 days to the lead time.
Can I finance the purchase of my new bike?
Yes. Simply select the Shop Pay Installments option which will allow you to buy now and pay later. Shop Pay Installments is powered by Affirm. If you would like to determine your spending limit, simply download the Shop app or the Affirm app on your smartphone and after you create an account on one of these apps, the app will let you know what is your spending limit.
Can I return the bike if it doesn't suit my needs?
Our return process is as follows. The customer is responsible for the return label ($150). Once the returned bike arrives at our warehouse, our team will inspect it and make sure it is in new condition and undamaged. Once we verify, we will process the return and issue a refund to the original payment method on file. To clarify the amount refunded, it would just be the amount of the bike (and tax if applicable) less the $150 shipping label that we provided, but the original shipping is not refunded. So if the original bike cost $4,500 and shipping was $150 (so you paid $4,650), you would be refunded $4,350 (the $4,500 less $150 for the return label) assuming the bike was returned in new and un-used condition and within the 30 day return period.
What does the warranty of my new bike or product cover and what is the warranty period?
Depending on the bike or any product, different companies have different warranty policies. If you do ever have an issue with your bike or any product, simply email us at online@victorybicyclestudio.com and we will assist with any warranty issues and clarify the warranty for the affected product.
Can I have my bike serviced at any bike shop?
Typically, to avoid any issues with your warranty, you should bring your bike to a certified mechanic or bike store for that bike (i.e. if you have a Trek bicycle, you should bring the bike to be serviced to a local bike store that is an authorized Trek dealer). If you need assistance, simply email us at online@victorybicyclestudio.com and we can direct you to a certified dealer of your bike.
Do you ship bikes internationally?
We unfortunately do not ship bikes outside of the 48 contiguous states of the United States. We do recommend for international customers to open (or use a current account) account with a freight forwarding company. If you use a freight forwarding company located in the U.S., make sure to put your billing address for a dedicated credit card as the same address as the freight forwarder so that you don't have any credit card or payment method issues).
Once you do this, simply place an order with us and we can ship to the U.S. address as long as the credit card doesn't get rejected. Once the freight forwarder has the box/order/shipment, you would instruct them to then ship to you in your home country and they would charge you their own shipping charge to ship to your international address.
Do you offer free shipping?
We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.
How much does shipping cost?
For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
How can I track my order?
When you place your online order, you will receive an instantaneous email update with your order number and order details, and shortly after, you will receive a follow up order email with the tracking number for your order. If you still need assistance with your order, feel free to email us at online@victorybicyclestudio.com and we will respond asap.
What happens if my package arrives damaged?
If your package arrives damaged, email online@victorybicyclestudio.com with pictures of all angles of the box and pictures of the damaged product and we will work with you to either send a new replacement asap and coordinate return (or re-imburse you for labor or costs incurred to fix the issue at your local bike store).
Are pedals included with the bike?
If you do not see pedals in the bullet point product specs on the product page, the bike does not come equipped with pedals. Many manufacturers do not spec bikes with pedals, so they are often purchased separately.
If I only pay the $150 for bike shipping, can I assemble the bike on my own?
Victory Bicycle Studio highly recommends that you bring your bike to your local certified bike store for the brand of the bike that you purchased. If you do attempt to assemble the bike and damage occurs, this may result in your warranty not being honored. For that reason, we do highly recommend to select our Professional Assembly option for $299.
