VIVI H7UL Electric Bike Review (2025): 27.5″ Off-Road Electric Mountain Bike

The VIVI H7UL is a 27.5″ high-step electric mountain bike built for riders who want a lightweight, hardtail eMTB that can handle daily commuting, weekend trail rides, and light off-road exploring. With a 1000W peak brushless hub motor, 48V 10.4Ah battery, and Shimano 21-speed drivetrain, it aims to blend trail-ready performance with everyday practicality.

It’s designed for riders roughly 5’2″–6’4″ who prefer a traditional high-step frame and want a bike that feels quick and efficient on pavement, gravel, and moderate mountain trails.

Ride Feel: Nimble Hardtail With Trail-Friendly Stability

Where some eMTBs feel bulky and sluggish, the H7UL leans toward the lighter, more agile end of the spectrum. At about 54 lb with the battery, it’s noticeably lighter than many fat-tire or long-travel eMTBs, which helps it feel more responsive when you stand up, lean into turns, or thread through tighter singletrack.

Key ride-feel points:

  • 27.5″ x 1.95″ tires keep rolling resistance lower than fat tires, while still offering enough volume for comfort and traction on gravel, dirt, and rough pavement.
  • The 60 mm coil-spring suspension fork takes the edge off rocks, roots, and potholes, making it suitable for daily commuting, road cruising, and trail riding.
  • The high-step 6061 aluminum frame and 27.5″ wheel size create a stable, predictable platform at 15–22 mph.

If you prioritize a bike that feels efficient on pavement but doesn’t get overwhelmed on rougher paths and moderate mountain trails, the H7UL’s hardtail setup hits a nice middle ground.

Motor, Battery & Real-World Range

The VIVI H7UL uses a 1000W peak brushless hub motor rated at 65 Nm of torque, powered by a 48V 10.4Ah (499.2Wh) lithium-ion battery.

On the spec sheet, VIVI lists:

  • Max range: up to 50 miles (80 km)
  • PAS range: 44–50 miles (70–80 km)
  • Throttle (ebike) range: 22–25 miles (35–40 km)

Elsewhere in the product highlights, VIVI notes that the 48V 10.4Ah battery can achieve 22–25 miles in pure electric mode and 44–50 miles in pedal mode on a single charge under ideal conditions.

In real-world mixed riding, it’s safer to plan on:

  • About 20–35 miles per charge, depending on:
    • Rider weight and cargo
    • Terrain and climbing
    • Wind and temperature
    • How often you use higher PAS levels or throttle

The included 54.6V 2A smart charger typically takes 4–6 hours to go from low to full, so overnight or workday charging is easy to integrate into your routine.

You get five PAS levels, a 12-magnet cadence sensor, and both half-twist and thumb throttle options, which give you fine control over how much effort you want to contribute versus how much you let the motor handle.

Comfort & Fit (Best for 5’2″–6’4″)

The VIVI H7UL is a high-step mountain bike frame, and VIVI recommends it for riders between 160–195 cm (about 5’2″–6’4″).

Key fit and comfort details:

  • Standover height: ~29.9″ (76 cm)
  • Seat height range: 33.1″–37.4″ (84–95 cm)
  • Handlebar height: 43.3″ (110 cm)
  • Max load: 330 lb (rider + cargo)

Comfort components include:

  • Ergonomic imitation leather grips that reduce hot spots on long rides
  • A breathable sport saddle designed to be supportive without feeling overly bulky
  • An adjustable alloy seatpost with quick-release clamp, making height tweaks easy

If you’re solidly within the height range and used to high-step frames, mounting and dismounting should feel normal. If you’re at the shorter end (around 5’2″) or have mobility concerns, it’s worth paying extra attention to that ~30″ standover height to ensure it feels comfortable and safe.

Utility & Everyday Practicality

Although the H7UL is marketed as an off-road electric mountain bike, it’s equipped to double as a practical everyday ride.

Out of the box, you get:

  • Full-coverage front and rear fenders to keep road spray under control
  • A heavy-duty side kickstand for stable parking
  • An optional rear rack (sold separately) if you want to carry panniers, trunk bags, or a small basket

With a 330 lb total capacity, there’s room for:

  • A backpack or panniers for commuting
  • Groceries or work gear when paired with a suitable rack
  • Light bikepacking loads, as long as you stay within rack and frame limits

For riders who split their time between office days, trail weekends, and general cruising, the H7UL can realistically replace many short car trips.

Safety, Brakes & Weather Protection

The H7UL includes a sensible safety package for a 2025 eMTB:

  • Brakes: 160 mm dual mechanical disc brakes with alloy levers and motor cut-off switches
  • Lighting: 48V integrated LED headlight plus rear reflector (most riders will still want an active rear light)
  • Bell: Integrated handlebar bell for audible alerts in traffic or on shared paths
  • Weather: IP54 rating (resistant to dust ingress and splashing water—fine for light rain and wet roads, but not submersion)

On the certification front, the bike’s electrical system is:

  • SGS tested
  • Certified to UL 2849 (full e-bike system) and UL 2272
  • Also listed with GCC and CPSC 1512 compliance

For buyers in 2025 who are paying closer attention to battery and electrical safety, especially in apartments or shared garages, those certifications are an important positive.

Drivetrain, Handling & Control

The VIVI H7UL combines a 21-speed Shimano drivetrain with its hub motor and PAS system to give you a wide range of gearing and control:

  • Derailleurs: Shimano RD-TZ500 rear + FD-TY300 front
  • Shifter: Shimano SL-TX50 7-speed thumb shifter
  • Gearing: 3 x 7-speed (21-speed total), 14–28T freewheel, 42T chainring, 170 mm crank

That setup means you can:

  • Spin comfortably on flat ground at 15–20 mph
  • Use low gears to climb hills without grinding
  • Drop assist entirely and ride it like an analog mountain bike if you want a workout

Control-wise, you get:

  • 5 PAS levels to dial in how much help you get
  • Half-twist + thumb throttle for pure-electric riding when you need it
  • Cruise control for holding a steady speed
  • Booster / assist push mode for walking the bike up ramps or short hills

Handling is stable yet reasonably nimble, thanks to the 27.5″ wheels, narrower 1.95″ tires, and relatively low weight for an eMTB. It feels more like a modern hardtail trail bike with power than a heavy, overbuilt e-moto.

Pros & Cons

Pros

  • 1000W peak brushless hub motor with 65 Nm torque for confident climbs and off-road use
  • 48V 10.4Ah (499.2Wh) removable battery with realistic 20–35 mile range in mixed riding
  • 27.5″ x 1.95″ tires and 60 mm suspension fork for efficient yet trail-capable performance
  • Shimano 21-speed drivetrain for flexible gearing on varied terrain
  • Dual mechanical disc brakes with motor cut-off levers
  • High load rating (330 lb) and rider height range of 5.2–6.4 ft
  • IP54 rating and UL 2849 / 2272-certified electrical system
  • Full-coverage fenders included; optional rear rack available

Cons

  • High-step frame and ~30″ standover height are not ideal for shorter riders or those who prefer step-through frames
  • Mechanical, not hydraulic, disc brakes—simple and functional but not as refined as hydraulic systems
  • No integrated rear light (reflector only); many riders will want an active rear light for visibility
  • No built-in USB charging ports for phones or accessories
  • Rear rack must be purchased separately if you want cargo carrying out of the box

Who the VIVI H7UL Is Best For

The H7UL is a good match if:

  • You’re between about 5’2″ and 6’4″ and comfortable with a high-step frame
  • You want a light-ish, nimble hardtail eMTB rather than a heavy fat-tire bike
  • Your rides mix pavement, gravel, and light-to-moderate mountain trails
  • You’re looking for a budget-friendly, UL-certified electric mountain bike with enough range for 10–30 mile rides
  • You like the idea of one bike that can commute during the week and hit trails on the weekend

Who Should Probably Skip It

You may want to look at other models if:

  • You strongly prefer a step-through or low-standover frame
  • You need to carry your bike upstairs frequently—54 lb is light for an eMTB but still not featherweight
  • You mostly ride tight urban traffic and want ultra-quick, city-bike handling with narrow slick tires
  • You routinely need 40–50+ miles at high speeds without charging
  • You specifically want hydraulic brakes, a torque sensor, or fully integrated rear lighting out of the box

In those scenarios, a step-through commuter, lighter city ebike, or higher-spec trail bike may fit your needs better.

Final Verdict: Is the VIVI H7UL Worth It?

If you’re looking for a 27.5″ hardtail electric mountain bike that can confidently handle off-road rides, daily commuting, and general fitness rides—without the extra weight and drag of fat tires—the VIVI H7UL is a strong contender.

You’re getting:

  • A torquey 1000W peak hub motor
  • A 48V 10.4Ah battery with realistic 20–35 mile range
  • 27.5″ x 1.95″ puncture-resistant tires and a suspension fork
  • Shimano 21-speed drivetrain and dual disc brakes
  • UL-certified electronics, IP54 weather protection, and practical extras like fenders and walk-assist

It’s not a premium enduro rig, and it’s not the lightest bike on the market, but as a versatile, trail-ready, and budget-conscious eMTB for riders 5’2″–6’4″, it delivers a lot for what you’re paying.
