Jasion RetroVolt 20-Inch Fat-Tire Moped-Style Electric Bike
Dry-weather neighbourhood riding on fat tyres
A 20 by 4 inch fat-tire, moped-shaped e-bike with dual suspension, seven gears and a 330-pound payload that all three sources agree on. They do not agree on the battery or motor: the listing says 48V 15Ah and 2000W peak, Jasion's page says 48V 18Ah, and the manual's table says 48V 12.5Ah and 750W. Confirm which you are getting before ordering.

Fit and limits
Strengths

- Battery is removable and the manual has a dedicated removal section
- Front wheel, pedals, fender and stem cover are the only parts to fit

- The manual tells you not to ride in wet conditions and excludes water damage
- No maker document read names a UL standard or a US e-bike class
A moped-style fat-tire bike that arrives mostly built
The RetroVolt is Jasion's retro, moped-shaped electric bike on 20-inch by 4-inch fat tyres, with dual suspension, disc brakes and a seven-speed rear derailleur. Amazon lists the model number simply as RetroVolt and names Galaxy Mobility Inc as the manufacturer. Jasion's own page for it is headed RetroVolt 330.
Amazon's included-components field lists the battery, a cargo rack, a charger, a mudguard, a tool kit and a user manual. The manual's package-contents page shows a manual flyer, two pedals, the charger, two keys, the front wheel, one fender, two wrenches, three Allen keys, a stem cover and the bike itself. So the front wheel, pedals, fender and stem cover are the parts you fit.
The manual asks you to unpack the bike with a second person capable of safely lifting a heavy object, which matches its stated package weight of 102 pounds. The listing claims the bike arrives 85 percent pre-installed. Budget time and floor space for the final assembly, and check every fastener before the first ride.
Three documents, three different motor and battery figures
This is the thing to settle before you buy. The Amazon listing says a 48V 15Ah removable battery and a 2000W peak motor. Jasion's RetroVolt 330 page says 48V 18Ah and 2000W, with its product heading calling the 2000W a peak figure. The manual's specification table says Battery 48V 12.5Ah and Motor 750W, and it does not label that 750W as nominal or as peak.
Those are three different battery capacities from three documents, and two very different motor numbers. We are not able to tell from what we read which revision of the bike any given order ships with, and we are not going to guess. Ask Jasion in writing which battery and motor your unit has before you order, and keep the reply.
The speed figures disagree too. Both the listing and the maker page say 30 mph. The manual's table says a maximum speed of 28 mph, or 45 km/h. Neither the maker page nor the manual pages we read assigns this bike a US class 1, class 2 or class 3 designation; the manual only tells riders to be aware of local road laws and follow them.
Range and charging are claims with no stated test conditions
The listing and the maker page both claim up to 70 miles of range. The manual's specification table instead gives a range of 55 to 65 miles, or 89 to 105 km. None of the three documents we read states the rider weight, terrain, assist level, temperature or tyre pressure behind any of those numbers, so treat every one of them as an unqualified claim.
Charging is the one figure that matches. The listing says a full recharge takes about five to six hours, and the manual's table gives a charging time of five to six hours with a 48V charger. The manual's contents page lists separate sections for removing the battery and for charging the bike, so the pack can be taken off and charged away from the bike.
The manual's safety page adds a practical warning about the two supplied keys: if you lose them you will not be able to turn the bike on or replace the battery, and it states plainly that no backup key is held. Order spare keys early rather than after you have lost the pair in the box.
Fit, weight and the 330-pound payload
Payload is the one headline that agrees everywhere: 330 pounds, or 150 kg, on the listing, the maker page and the manual's table. The listing's bullets give a rider fit of roughly five foot four to six foot three. Amazon's structured minimum-user-height field reads 5.4 inches, which is plainly a data-entry error in the listing rather than a real measurement.
Jasion's page publishes frame geometry in centimetres: a 113.5 cm wheelbase, 170 cm total length, 46 cm reach, 69 cm standover, a saddle adjustable between 86 and 102 cm and handlebars between 120 and 130 cm. The page warns of a zero to five centimetre difference between measured and actual data, so measure your own garage or lift before ordering.
Bike weight is another place the documents part company. Amazon's table says 75 pounds and the manual says 82 pounds, or 37 kg, with the packed carton at 102 pounds. Either way this is not a bike you carry upstairs or hang on a wall hook, and any car rack should be checked against the heavier figure.
The water claims and the manual's wet-riding warning clash
The Amazon title includes IPX6. The manual's specification table gives an IP level of IP65. Those are different ratings and they come from different documents, so do not assume either one has been verified for the bike you receive; ask Jasion which rating applies to your revision.
More importantly, the manual's own product-safety page tells riders not to ride in wet conditions and states that wet conditions may damage the electronics and void the warranty. That instruction sits awkwardly beside a water-resistance rating printed in the same document, and the warranty pages separately exclude water damage.
If you are buying this to commute year-round in rain, read that page first and decide whether you accept the risk. The safety page also covers the usual helmet, sobriety and pedestrian rules, and we are not reproducing the full safety list here; read it in the manual before the first ride.
Warranty and returns: short window, long exclusion list
Amazon's warranty field says one year and Jasion's product page carries a one-year warranty badge. The manual's warranty section covers the original purchaser only, says the warranty ends if the bike is sold or transferred, and refers to defects in materials and workmanship for a period it calls aforementioned without restating a duration on the pages we read.
The covered-component list is long: battery, frame, forks, stem, handlebar, headset, seat post, saddle, brakes, lights, bottom bracket, crank set, pedals, rims, wheel hub, freewheel, cassette, derailleur, shifter, motor, throttle, controller, wiring harness, LCD display, kickstand, reflectors and hardware. Exclusions cover tyres, tubes, brake pads, cables and housing, grips, chain and spokes as consumables.
The manual also excludes damage from accident, misuse, commercial use, improper assembly, unauthorised service or parts, extreme and stunt riding, and water damage, and it says the battery is not warranted against power surges, an improper charger or poor maintenance. Returns run 14 days from receipt, need an authorisation number from Jasion's support address, require under ten miles on the odometer, and the customer pays return shipping.
