You searched for an “E500 electric bike review.” Here is the problem with that search: there is no single E500 electric bike.
“E500” is a model name, not a bike. On Amazon it is sold under at least two different brand names — RPINT and ASKMY — and the listings don’t just disagree with each other. In several cases, listings from the same brand disagree with themselves on battery size, motor rating, suspension, and load capacity.
This page does what no competitor currently does in one place: it identifies each E500 version from its actual listing, shows you exactly where the spec sheets contradict each other, and tells you how to make sure you buy the bike you think you’re buying.
The short version: two brands, one model name, zero consistency
Here is what the listings establish as fact:
- RPINT sells an “E500” on Amazon (multiple listing pages, part number E500-01 on the paperwork).
- ASKMY sells an “E500” on Amazon (ASIN B0FZFN25HD) and on its own site, askmybike.com.
- Both brands’ Amazon paperwork names the same manufacturer: Huizhou ENSMAI Intelligent Technology Co., Ltd. That strongly suggests one white-label bike sold under multiple brand names, with each seller writing its own spec sheet — which is exactly why the numbers don’t line up.
The practical consequence: the “E500” you receive is defined entirely by the listing you buy from. Everything below is labeled by source so you can see what is consistent, what is merely claimed, and what is contradicted.
The RPINT E500: what its listings actually claim
Compiled from RPINT’s Amazon listing pages. Where the brand’s own pages disagree, that is flagged — not smoothed over.
| Spec | RPINT listing claims | Status |
|---|---|---|
| Motor | 1000W peak brushless rear hub motor | Consistent across RPINT listings (claimed) |
| Battery | 48V removable — 15Ah on one listing, 18Ah (UL 2849) on another | Contradicted — check your listing’s spec table |
| Range | 35 miles pedal-assist / 25 miles electric | Claimed, favorable conditions |
| Tires | 20″ × 4″ fat tires | Consistent |
| Suspension | Front fork on one listing; “dual suspension” in another listing’s feature list | Contradicted |
| Brakes | Disc brakes | Consistent (mechanical at this price) |
| Gears | 7-speed | Consistent |
| Max load | 330 lbs on one listing, 300 lbs on another | Contradicted |
| Rider height | 5’4″ – 6’2″ | Consistent |
| Weight | 36.5 kg (~80 lbs) | Consistent |
| Top speed | 30–40 mph (listing claim) | Claimed — treat with skepticism; check local speed laws |
The ASKMY E500: what its listings actually claim
Compiled from ASKMY’s Amazon listing (ASIN B0FZFN25HD) and askmybike.com. Same story: the brand’s own pages disagree on the important numbers.
| Spec | ASKMY listing claims | Status |
|---|---|---|
| Motor | 1000W motor, 1500W peak (askmybike.com); some Amazon listings say 750W peak | Contradicted |
| Battery | 48V 15Ah / 768Wh (askmybike.com); 48V 20Ah on another ASKMY page | Contradicted — the single most consequential difference |
| Range | 45 miles (askmybike.com); 40–60 miles pedal-assist / 25–28 electric on other listings | Contradicted; all are favorable-condition claims |
| Tires | 20″ × 4″ fat tires | Consistent |
| Suspension | Front fork; some listings claim front and rear | Contradicted |
| Drivetrain | 7-speed, Shimano derailleur (per some listings) | Claimed |
| Brakes | Disc brakes | Consistent |
| Max load | 330 lbs | Consistent |
| Certification | UL 2849 claimed | Claimed — both brands claim it |
| Extra claims | Torque sensor, cruise control (brand site only) | Unverified elsewhere |
Side by side: what the two brands agree on
Strip away the contradictory numbers and the shared DNA is clear — which is exactly what you’d expect from one white-label bike:
| RPINT E500 | ASKMY E500 | |
|---|---|---|
| Class | 20″ fat-tire e-bike, ~80 lbs, 48V removable battery, 7-speed, disc brakes | |
| Fit | ~5’4″–6’2″ rider height, ~330 lb-class max load | |
| Manufacturer paperwork | Huizhou ENSMAI Intelligent Technology Co., Ltd (both brands) | |
| Battery capacity | 15Ah or 18Ah (listings disagree) | 15Ah or 20Ah (listings disagree) |
| Peak power framing | 1000W (consistent) | 750W / 1000W / 1500W (listings disagree) |
| Range claims | 35–40 miles PAS | 40–60 miles PAS |
Nothing in that table is a measured fact — it is all listing claims, and the honest version of this bike’s spec sheet has “unverified” written next to the battery, the motor peak, and the suspension. Plan your purchase around the consistent parts (fat tires, weight, fit, 48V removable pack) and verify the contradictory parts on the exact page you’re buying from.
The warning that matters: reviews don’t transfer between listings
This is the reason this page exists. A 4-star average on the RPINT listing tells you nothing about the ASKMY unit, and vice versa. Different ASINs, different sellers, possibly different batteries and suspension — sharing only a model name. When you read E500 reviews, check which listing the reviewer bought from. A review of the wrong version is worse than no review: it’s false confidence.
How to tell which E500 you’re looking at
- The brand name at the top of the Amazon listing — RPINT, ASKMY, or unbranded. This is the single most important identifier.
- The ASIN in the product details (ASKMY’s is B0FZFN25HD). If a review doesn’t match your ASIN, ignore it.
- The battery amp-hours in the spec table — 15Ah vs 18Ah vs 20Ah is the most consequential real difference between listings, and it directly affects range.
- The part number — E500-01 appears on RPINT’s paperwork.
Whichever E500 you buy, here’s what the bike itself is like
The versions differ on paper, but the underlying machine is the same class of bike. Here’s that machine, translated honestly:
Motor: 1000W-class peak (listed at 750W rated on some pages). Peak wattage is the burst power for starts, steep climbs, and getting up to speed — it’s what you’ll feel. Rated wattage is what the motor sustains. In practice, this much hub-motor power means confident takeoffs and decent hill help even for heavier riders, though it won’t feel like a motorcycle. On flat city streets it’s more than you need; it earns its keep on hills, headwinds, and soft surfaces like sand and snow.
Battery: 48V removable — but capacity is the thing to verify. Every listing agrees on 48V and a removable pack (handy for indoor charging and eventual replacement). Capacity is where they diverge, so don’t bank on a watt-hour figure until you’ve read your listing’s spec table — it’s the only spec that counts.
Range: advertised up to ~35–60 miles pedal-assist depending on the listing. Those are manufacturer claims under favorable conditions (lighter rider, low assist, flat ground). Real-world range depends on rider weight, assist level, terrain, temperature, and tire pressure. The honest planning rule: expect roughly half to two-thirds of the advertised pedal-assist figure in mixed real riding.
Tires: 20″ × 4″ fat tires. The defining feature — grip and float on sand, snow, gravel, and rough trails, plus built-in cushioning. The price is rolling resistance and weight: on smooth pavement a fat-tire bike feels slower and hungrier for battery than a skinny-tire commuter. If most of your riding is paved, the fat tires are fun but inefficient; on beaches, snow, or rough paths, they’re the whole point.
7-speed drivetrain. With this much motor you won’t need many gears, but seven speeds are genuinely useful: efficient pedaling at speed, crawling up hills without overtaxing the motor, and getting home if the battery dies. A working drivetrain is what separates an e-bike from an expensive paperweight when the charge runs out.
Brakes: front and rear disc (mechanical). Standard at this price — adequate and easy to service, but not the one-finger stopping power of hydraulics. On an ~80 lb bike capable of ~28 mph, give yourself extra following distance and keep the pads adjusted.
Weight: ~80 lbs; charging takes 5–6 hours. This is a heavy bike — stairs, car racks, and lifting are all a project, and it’s unpleasant to pedal unassisted for long. Budget an overnight or workday charge.
Honest limitations
- It’s heavy (~80 lbs). Carrying, stairs, and car racks are all a project.
- Budget components. Mechanical brakes, generic suspension, and a budget-brand frame are normal at this price — don’t expect premium fit-and-finish.
- Specs vary by seller — suspension type, battery capacity, and even the brand name differ between listings using the “E500” model name. Verify the page you’re buying from.
- Assembly is on you. These bikes ship mostly assembled, but you’ll need basic tools and mechanical confidence for the final setup.
- Check your local speed laws. Listings advertise speeds up to ~28–40 mph (some inflate this). That can put the bike in a different legal class depending on where you live.
- After-sales support is a question mark. Multi-seller budget brands don’t have dealer networks. Buy expecting to be your own mechanic or to pay a local shop.
Who should NOT buy an E500
- You need to carry the bike upstairs or lift it regularly.
- You ride almost entirely on smooth pavement — a lighter commuter e-bike will be faster and more efficient.
- You want a recognized brand with a dealer network and easy warranty claims.
- You’re much taller than ~6’2″ or much shorter than ~5’4″ — the compact 20-inch frame may not fit.
- You want hydraulic brakes or premium components.
- You can’t verify which listing’s specs you’re actually buying — don’t gamble on the contradictions above.
Alternatives worth a look
- TST Electric Bike review — a 1500W-peak fat-tire e-bike if you want even more power for hills and rough terrain.
- XPlorer 750W review — a 750W-peak option at a likely lower price if the E500’s power is overkill for your riding.
- Mongoose Argus Trail & ST review — if you’d rather buy a fat-tire bike from an established bike brand.
- Jasion EB5 review — if you realize you mostly want a commuter, not an all-terrain machine, this 26-inch budget commuter is lighter and simpler.

Verdict
Don’t buy “an E500.” Buy a specific listing — and read its spec table like a contract, because that’s what it is. The underlying bike is a lot of machine for the money: fat tires, strong peak power, a removable 48V battery, and a generous load rating in a compact frame. But the model name is shared by sellers whose spec sheets contradict each other on battery size, motor rating, and suspension. Identify your version using the checklist above, verify the battery amp-hours, and you’ll know exactly what you’re getting.
