💰 $899.99 $1,399.99 | Save $500Why the VIVI ACE07 Is the Mountain Ebike to Buy in 2026
If you've been searching for a mountain ebike that delivers serious performance without a four-figure price tag, your search ends here. The VIVI ACE07 packs a 1475W peak brushless motor, 90Nm of torque, a massive 720Wh removable battery, and 26″ × 4.0″ all-terrain fat tires — all at a sale price of $899.99 (down $500 from retail). And it ships free to every US state in as little as 2 business days.
For context: most mountain ebikes at this price compromise somewhere — an undersized battery, a weak motor, or no safety certifications at all. The ACE07 skips all of that. With dual SGS certifications (UL2849 + UL2271), this is one of the safest, most capable fat tire mountain ebikes under $1,000 currently available in the US market.

What Makes the VIVI ACE07 the Best Mountain Ebike Under $1,000
1475W Peak Motor — More Power Than Most "2000W" Hub Motors Deliver
The ACE07's rated 750W motor surges to 1475W peak output on demand — hill climbs, sudden acceleration off-road, and loaded hauling scenarios where budget motors bog down completely. The 90Nm torque figure is the real headline: it's what you feel when you hit a 15% grade and the bike pulls cleanly through it without you standing on the pedals. Most mountain ebikes priced under $1,000 top out at 40–60Nm. The ACE07 is in a different class.
4.0-Inch Fat Tires — The Core of the Mountain Ebike Experience
Fat tires aren't just an aesthetic choice on a mountain ebike. Running at just 8–15 PSI (versus 60–80 PSI on a road bike), the ACE07's 26″ × 4.0″ tires create a footprint roughly four times larger than a standard tire. That translates to dramatically better traction on gravel, sand, packed dirt, roots, and wet pavement — terrain where narrow-tire bikes slide or bounce. Pair that contact patch with the 100mm front suspension fork and you have a ride quality that feels planted and predictable on surfaces that would unsettle most commuter ebikes.
720Wh Battery — Enough Range to Stop Thinking About Range
The ACE07's 720Wh Samsung-cell battery is one of the largest in its price bracket. In practical terms: 10-mile daily commuters go 6 days between charges. A 25-mile weekend trail loop is a single-charge round trip with range to spare. The battery is fully removable — unplug it and charge it at your desk, or leave it on the bike. The included smart charger completes a full cycle in 4–6 hours.
UL2849 + UL2271 Certified — Why Safety Matters When Buying a Mountain Ebike
The US ebike market is flooded with uncertified imports. Battery fires, electrical failures, and fraudulent wattage claims are real and documented issues. The VIVI ACE07 carries both UL2849 (complete electrical system) and UL2271 (lithium battery pack) certifications from SGS — one of the most respected third-party safety laboratories in the world.
Who Should Buy the VIVI ACE07 Mountain Ebike?
The ACE07's step-through frame and all-terrain capability make it genuinely versatile. Here's who benefits most:
🏙️ Daily Commuters
60-mile range, rear rack compatibility, and fat tires that absorb potholed city streets
🏔️ Trail Riders
4.0″ tires + 100mm fork + 1475W peak handle gravel paths, forest dirt, and moderate off-road
🧑 Riders Over 50
Step-through low standover frame eliminates the leg swing — easier mounting at every stop
💪 Heavier Riders
330 lb max load capacity covers a wide range of adult riders plus cargo comfortably

Frequently Asked Questions — VIVI ACE07 Mountain Ebike
Is the VIVI ACE07 a true mountain ebike or mainly a commuter?
Both. The ACE07 is designed as an all-terrain step-through — it handles gravel, forest trails, beach sand, and packed dirt as confidently as city streets. The 4.0″ fat tires, 1475W peak motor, and 100mm suspension fork provide genuine off-road capability. It's not a full-suspension downhill race bike, but for trail exploration, loaded touring, and daily commuting — it's one of the most versatile mountain ebikes under $1,000 on the market.
How fast does the VIVI ACE07 ship across the USA?
VIVI processes orders within 2 business days from their US warehouse. Delivery to any US state takes 3–7 business days. Free shipping is included on every order — no minimum, no state restrictions. The bike arrives packaged with assembly tools; only basic setup (handlebars, pedals, front wheel) is required.
What is the real-world range of the VIVI ACE07?
VIVI's official range is up to 60 miles on PAS1 and 28–34 miles on throttle-only. In real-world mixed conditions (hills, stops, mid-level assist), most riders report 25–45 miles per charge — excellent for a fat-tire mountain ebike at this price. The 720Wh battery is removable for indoor charging convenience.
Is the $899.99 sale price still valid?
As of this review (March 2026), the VIVI ACE07 is listed at $899.99 — reduced from $1,399.99, saving $500. Anniversary sale code SALE50 provides an additional $50 off at checkout. Pricing is subject to change; click the link to confirm the current price on viviebikes.com.
Does the VIVI ACE07 come with a rear basket option?
Yes. The ACE07 is available in two configurations: standard Ebike and "with Rear Basket." Both are offered in all five color options (Space Black, White, Midnight Blue, Olive Green, Icy Grey). The basket version is slightly higher priced. Check viviebikes.com for current availability.
Final Verdict — VIVI ACE07 Is the Mountain Ebike Benchmark Under $1,000
After analyzing every spec, comparing it against the competition, and reviewing rider feedback, the conclusion is clear: at $899.99 on sale, the VIVI ACE07 delivers a combination of motor power (1475W peak), range (60 miles), battery capacity (720Wh), tire capability (4.0″ fat), and safety certification (UL2849 + UL2271) that no other mountain ebike at this price point currently matches.
Tackling Rocky Mountain trails, Midwest gravel paths, Florida beach rides, or potholed city blocks — the ACE07 handles it with the same planted confidence. With $500 off retail and free shipping to every US state, March 2026 is the best time to order one.
