Design & Intent: Retro Moped Styling Meets Family Cargo Use
The TST R7 combines retro moped styling with a step-through / low step-over frame and a long bench-style seat. The idea is to give you:
- A bike that’s easy to mount and dismount, especially for women, older riders, or anyone with limited mobility
- A stable platform for city streets, light trails, and neighborhood riding
- A rear setup that can handle passengers or cargo
Key design touches from the brand:
- Full suspension (front and rear) to smooth out bumpy roads, with adjustable rebound and a lockout so you can firm things up when you want better pedaling efficiency
- 20″ x 4.0″ all-terrain fat tires that are puncture-resistant, anti-slip, and feature reflective safety strips for better night visibility
- A modular rear system: use the rear seat for a passenger, or swap it for a cargo rack or storage box, depending on how you ride
TST explicitly calls out the R7 as being designed for families, women, seniors, and beginners who want something comfortable, confidence-inspiring, and practical for everyday rides.
👉 See how TST frames the R7 as a family and cargo bike on the product page.
Motor, Battery & Real-World Range
The R7 is built around a 1500W high-torque brushless rear hub motor delivering up to 90 N·m of torque. For a compact 20″ wheel, that translates into:
- Strong pull away from stops, even with a passenger or full cargo box
- Confident hill-climbing on typical city grades
- A top speed up to 32 mph when fully unlocked
Because 32 mph is above typical Class 3 limits (28 mph) in many areas, it’s important to check your local e-bike and moped rules. In some regions, you may need to treat the R7 more like a moped than a standard Class 3 e-bike, or limit speed in the settings.
Power comes from a 48V 15Ah (720 Wh) removable, lockable battery mounted in the frame. The brand claims a maximum range of up to 65 miles per charge, with a 5–6 hour charge time using the included 54.6V / 2A charger.
Realistic Range Expectations
The 65-mile number is a best-case scenario. Given the 720 Wh battery, 1500W motor, 82+ lb bike, fat tires, and the likelihood of carrying extra weight, most riders should plan around:
- Roughly 25–45 miles per charge in mixed conditions
For example:
- A single rider on flatter routes using PAS 2–3 and pedaling steadily might see 35–45 miles
- A rider frequently using higher PAS or throttle, plus a passenger or loaded storage box, is more realistically in the 25–35 mile range
If you regularly haul a passenger, groceries, or gear, it’s smart to plan around 30–35 miles and treat anything above that as a bonus.
👉 Check the R7’s motor, range, and battery details directly on the TST page.
Riding Modes, Assist & Controls
The R7 gives you several ways to ride:
- 1–5 levels of pedal assist (PAS 1–5)
- Throttle for no-pedal riding when you want it
- Four riding modes, including a Boost Mode that provides extra assistance when starting off or on gentle climbs
TST’s copy emphasizes ease and control when the bike is loaded with groceries or gear:
- Lower PAS levels are for cruising and maximizing range
- Higher PAS and Boost Mode are there when you need extra push—starting on a hill, carrying a passenger, or pulling away from a stop sign with confidence
The R7 uses cadence/speed-based assist rather than a torque sensor. In practice:
- Assist kicks in based on how fast the cranks are turning and what level you’ve selected
- You get predictable, strong assist once the system sees you pedaling, with the throttle available as a “go now” button
An LCD display sits up front, showing speed, distance, battery level, and assist level, so you can track your ride and battery at a glance.
Brakes, Suspension & Safety
For a compact cargo/capacity bike, stopping power and comfort matter as much as power.
The R7 comes with:
- 180 mm hydraulic disc brakes front and rear
- Full suspension – front fork and rear shock – with adjustable rebound and a lockout mode
Hydraulic brakes on 20″ fat tires give you:
- Strong, controllable braking with less hand effort
- More confident stopping in wet, dusty, or variable conditions
- Better heat management on long descents than smaller or mechanical setups
The full-suspension setup helps:
- Keep the bike composed on broken pavement, speed bumps, and light off-road use
- Maintain traction when turning or braking on rough surfaces
- Reduce fatigue for riders with sensitive backs, shoulders, or wrists
The bike is also:
- UL 2849 certified for e-bike system safety
- SGS certified (c us 803623)
Integrated front and rear lights and reflective side strips on the tires round out the visibility package.
Fit, Geometry & Comfort
The R7 is a compact moped-style bike rather than a full-length traditional frame. From TST’s geometry chart:
- Total length: 61.5″
- Handlebar height: 42.9″
- Wheelbase: 38.1″
- Stand height: 31.2″
- Minimum seat-to-floor height: 31.5″
- Handlebar length: 26.7″
- Seat length (bench): 22.5″
In real terms, that means:
- A shorter overall length than many full-size cargo bikes
- A low step-over that makes mounting and dismounting easier
- A wide, bench-style seat that’s more about relaxed riding and passenger comfort than aggressive pedaling
TST highlights that the low step-over frame and full suspension make the R7 especially comfortable for women, seniors, and beginners. If you’re significantly shorter or taller than average, it’s still worth matching the 31.2″ stand height and 31.5″ seat-to-floor figures against your inseam.
Utility & Cargo: Modular Rear System and Load Capacity
Utility is where the R7 leans in hard:
- Max load: 450 lb – bike + rider(s) + cargo
- Modular rear system:
- Rear passenger seat by default
- Rear rack (included in the box)
- Optional storage box for groceries, tools, or delivery setups
TST’s positioning is very clear:
- Use it as a family bike with a passenger on the rear bench
- Swap to a rack or box for grocery runs, school runs, or commuting with gear
In real life, that looks like:
- School drop-offs with a child on the back and a backpack strapped to the rack
- Weekly grocery runs with a full storage box and a couple of reusable bags bungeed on
- Commuting with a laptop bag, lunch, and a change of clothes in the box—without starting the car
What’s in the box (per the brand):
- Electric bike
- Battery with keys
- Charger
- Two seats (front main + rear seat)
- Rear rack
- Fender set
- Headlight
- Front wheel
- Pedals
- Owner’s manual
- Wrenches and Allen keys
- Rear foot pegs
Most riders can assemble and configure the bike at home, then choose whether the rear is set up for passengers or cargo.

Pros & Cons
Pros
- 1500W high-torque rear hub motor (90 N·m) for strong acceleration and hill climbing
- 48V 15Ah removable battery with a claimed 65-mile range and realistic ~25–45 miles for most riders
- Full suspension front and rear with adjustable rebound and lockout
- 20″ x 4.0″ fat tires that are puncture-resistant, anti-slip, and include reflective safety strips
- 180 mm hydraulic disc brakes for strong, predictable stopping
- 450 lb max load and modular rear system (passenger seat, rack, optional storage box)
- Low step-over frame explicitly marketed as comfortable for women, seniors, and beginners
- UL 2849 and SGS (c us) safety certifications, plus app support and 1-year warranty
Cons
- At around 82.67 lb, it’s not a bike you’ll want to carry upstairs regularly
- Moped-style ergonomics are great for comfort and cargo, less ideal if you want a sporty, pedal-focused ride
- 32 mph top speed pushes it beyond typical Class 3 limits in many regions—local rules may treat it closer to a moped if left fully unlocked
- Single general size; no brand-provided rider-height range, so very short or very tall riders should double-check fit against the geometry numbers
- Cadence-based assist (not torque-sensor), so power delivery is less “road-bike natural” than on premium mid-drive systems
Who the TST R7 Is Best For
The R7 is a strong fit if:
- You want a moped-style, full-suspension cargo/family e-bike with serious power
- You plan to carry a passenger, groceries, or work gear regularly and need a higher load rating
- You value a low step-over, comfortable seat, and full suspension more than aggressive pedaling dynamics
- You like the idea of a compact 20″ platform that can weave through city streets but still feel stable and planted
- You’re comfortable checking local rules around a 32 mph-capable motor and riding accordingly
Who Might Want to Skip It
You might be better off with another style of e-bike if:
- You need something very light to carry up stairs or onto transit regularly
- You ride mostly long-distance fitness or performance rides and prefer a more traditional, pedal-forward geometry
- You want a pure Class 1/2/3 commuter that clearly fits within standard legal classifications, without tweaking speed settings
- You’re well outside average height ranges and require a more adjustable frame with clearly defined rider size recommendations
In those cases, a lighter commuter or standard-frame cargo bike may suit you better.
Final Thoughts: Is the TST R7 Worth It?
If you’re looking for a full-suspension, moped-style electric cargo bike that can carry real weight, stay comfortable over rough city streets, and still feel approachable for less experienced riders, the TST R7 checks a lot of boxes.
You’re getting:
- A 1500W, 90 N·m rear hub motor and 48V 15Ah battery
- Claimed up to 65 miles of range, with realistic expectations around 25–45 miles depending on how you ride
- Full suspension, hydraulic disc brakes, and 20″ x 4.0″ fat tires for traction, comfort, and control
- A 450 lb max load rating with a modular rear system that can be set up for passengers or cargo
- Safety certifications, integrated lights, and a design aimed squarely at families, women, seniors, and everyday riders who want comfort first
