Jasion Electric Trike

The 30-second verdict

Most budget trikes ask you to choose between a safety certificate and a low price. This one does not. Jasion states UL 2849 — the system-level standard that fire codes reference — on a $499.99 machine, which is the lowest price we have seen that wording attached to. Around it sits a genuinely complete spec sheet: a 500W rated motor (1,200W peak), a 624Wh battery, a rear differential so the trike corners properly, 18" wide tyres, front and rear baskets with the covered rear one rated to 77 lbs, and a 400 lb total load capacity that includes the rider. The seat is oversized with a backrest and adjusts across a 4'9" to 6'3" fit range, which is wider than most and the reason this machine keeps appearing in senior-mobility searches. The catch is a 16 mph top speed — deliberately below the 20 mph Class 2 ceiling. On three wheels that restraint is a feature, but it is a real difference from the 20 mph trikes beside it.

Why the certificate is the headline

Battery fires cluster in exactly the population trikes sell to. Riders who buy three wheels are disproportionately likely to charge indoors — an apartment hallway, a condo storage room, a garage attached to the house — because they are often riders for whom carrying a battery up stairs is the point of not having two wheels. UL 2849 is the whole-system electrical safety standard, covering the battery, charger and controller together rather than cells in isolation. It is the standard New York City's Local Law 39 regime made effectively mandatory for indoor charging, and the one California SB 1271 ties to what may legally be sold in the state from 2026. On the NARRAK folding trike the battery is called "certified" with no standard named; here the number is printed. At this price that is the single most valuable line on the listing.

The 16 mph decision

Jasion caps this trike at 16 mph, and it is worth understanding what that buys and costs. Class 2 — throttle-equipped, motor cutting out at 20 mph — is the definition nearly every state copies from the federal framework, and a 16 mph machine sits comfortably inside it. That means no wattage question (500W rated is under the 750W cap in 49 states and Oregon's 1,000W allowance), no class-restriction question, and no jurisdiction in our 52-state table where this trike is anything other than a legal e-bike. It also means you will be overtaken by 20 mph bikes. Three wheels corner by leaning the machine rather than the rider, and speed is where trikes get genuinely unstable, so we read the 16 mph cap as engineering judgement rather than a missing feature. Buyers who want 20 mph on three wheels should look at the 750W NARRAK.

Range: the listing claim versus the arithmetic

Jasion quotes up to 55 miles in pedal-assist mode. Check that against the pack. 624Wh ÷ 55 miles = 11.3 Wh per mile, and a fat-tyred trike carrying a rider upright does not achieve 11 Wh per mile — 18-25 Wh per mile is the honest band once you account for the third tyre, the upright riding position and the weight. The realistic figure is 624 ÷ 24 ≈ 26 assisted miles, and closer to 18 on throttle alone with the rear basket loaded. The 55-mile number is a minimum-assist, flat-ground, light-rider lab figure. This is not a Jasion-specific sin — nearly every listing in this category quotes range the same way — but it is the number most likely to disappoint, so plan errand loops around 25 miles and treat anything beyond as a bonus.

Load, fit and the parts that get used daily

The 400 lb total capacity is the most useful number Jasion publishes, and almost nobody else in this bracket publishes one at all. It includes the rider, so a 200 lb rider has roughly 200 lb of headroom for cargo — comfortably more than a weekly shop. The covered rear basket is separately rated to 77 lbs, and the cover matters more than it sounds: an open basket on a trike is where shopping bounces out on a kerb. The seat is the other daily-use win, with a backrest and a 4'9" to 6'3" adjustment range that spans most adults, and a step-through frame so mounting does not require swinging a leg over anything. Controls are a large colour LCD with five assist levels and three modes — pure electric, pedal-assist and manual — which is the right amount of complexity for this buyer.

What is missing

No weight is published, which matters on a trike you may need to move by hand. Brakes are mechanical discs with a parking lock — confirmed on Jasion's own JT18 product page, which also names a Shimano 7-speed drivetrain, front suspension and cruise control that the Amazon listing never mentions. The parking lock matters on a trike, which cannot be held still with a foot; the 750W NARRAK goes further with full hydraulics. There is one figure worth pausing on: Amazon advertises a 400 lb total capacity and Jasion's own site says the maximum payload is 300 lbs. We publish the lower number, because a load rating is a safety limit and the manufacturer's page is the better source for it. And Jasion, despite being one of the largest brands on Amazon's e-bike chart, sells through the storefront rather than a dealer network: warranty service is a support ticket, not a workshop.

Who should buy it

Riders who want a certified battery at the lowest possible price, seniors and returning riders who need the wide fit range and the backrest, and anyone whose building or insurer asks for battery paperwork. Skip it if you want 20 mph, if you need hydraulic brakes for a hilly route, or if you have no trike-sized storage.
