Addmotor Citytri E-310 Folding eTrike: Fold in Seconds and Explore the Outdoors Your Way

1. Stop Compromising: An Electric Trike That Truly Goes With You

Ever tried fitting a full‑size trike in your trunk? It’s a headache you don’t need. Or maybe you’d love to take your parents to the park, but worry they’ll struggle to get on and off. And if you live in an apartment, where on earth would you park a bulky, heavy electric tricycle?

The Addmotor Citytri E-310 folding electric trike was built to break these limits.

This isn’t the old‑school, space‑hogging mobility aid meant only for seniors. It’s a personal adventure companion that folds in seconds and unfolds for fun. Whether you’re tossing it in your SUV for a weekend camping trip, riding to the grocery store, or just cruising the neighborhood, the Citytri E-310 folds down small enough to fit in an SUV trunk, an RV compartment, or even a corner of your apartment balcony.

This is “Outdoors Your Way” — explore on your own terms.

2. Fold in Seconds, Go Anywhere

The folding design isn’t a gimmick — it solves real problems.

No tools. No manual. One simple lift and the whole frame folds flat. How small?

A typical SUV trunk is about 40 inches deep. The folded Standard version fits easily sideways or diagonally. If you drive an MPV or pickup, you can roll it straight in. At 86 lbs (including the battery), it’s a solid, road‑ready machine. While manageable for most adults to lift into a trunk, its real magic is how easily it rolls once unfolded.

Picture this: Saturday morning, fold the Citytri E-310, toss it in your trunk, drive two hours to a national park. Park the car, unfold this foldable electric trike, hit the battery button — and within seconds you’re riding a forest trail. When you’re done, fold it back up and drive home. No trailer hitch, no hassle.

The frame is 7020+6061 aircraft‑grade aluminum alloy — light, strong, and shock‑absorbing. The low step‑through (standover height just 13.8–16 inches) means you don’t swing a leg over — just sit down. That’s a game‑changer for seniors or anyone with stiff joints.

3. The Heart of Power: Safe, Strong, and Reliable

The biggest worry for buyers of electric tricycles for adults is battery safety. The Citytri E-310 has you covered with double protection:

• The entire electrical system is UL 2849 certified — the gold standard for e‑bike electrical safety in the U.S.
• The battery uses Samsung 48V 20Ah cells and is UL 2271 certified — tested for shock, overcharge, short circuits, and more.

So the heart of this foldable electric tricycle for adults combines premium cells with serious safety certs. Charge at home with confidence.

Range and power? In PAS 1 (most efficient assist), a single charge gets you 90 miles. That’s like riding from downtown Manhattan to Philadelphia with juice left over. For daily errands or park rides, you might only need to charge once a week.

The 750W rear‑drive motor delivers serious torque. It’ll climb grades over 15% without breaking a sweat. Live in a hilly city like San Francisco? This adult e trike won’t leave you pushing.

Charging is a pleasure: the 5‑pin magnetic charging port is a stroke of genius — no more fumbling with tiny pins in a dark garage. It snaps into place effortlessly, making the charging routine as simple as plugging in your MacBook.

4. Control at Your Fingertips: From Leisurely Cruising to Instant Burst

The Citytri E-310 gives you three ways to ride:

• 7‑level pedal assist — dial down for a workout, dial up for effortless cruising. The cadence sensor delivers smooth, linear power — no jerky surprises.
• Half‑twist throttle — don’t feel like pedaling? Just twist and go. Perfect for starting at a stoplight, crossing an intersection, or adding a boost before a hill.
• 5‑inch LCD display — speed, battery, assist level, mileage. Large fonts, readable in direct sunlight.

Example: Ride to your favorite fishing spot. On the way there, use the throttle with a full battery and arrive fresh. On the way back, with half a battery left, switch to PAS 2 and pedal leisurely home while watching the sunset. No fatigue, but you still get some exercise. Top speed is 20 mph — compliant with e‑bike laws in most U.S. states.

5. Rock-Solid Stability: The Chassis Secret of This 3 Wheel Electric Bike

Think trikes tip over easily? That’s because most lack a critical component: a differential.

The Citytri E-310 has a rear axle differential. When you turn a corner, the two rear wheels spin at different speeds — the outside wheel faster, the inside slower. This lets the trike lean naturally into the turn instead of being “pushed” over.

Bottom line: you can corner faster and safer on this folding electric tricycle than on any ordinary trike.

Every wheel gets its own mechanical disc brake. Three independent discs mean stopping power far beyond a two‑wheel e‑bike. Long downhill? No problem — control your speed calmly without brake fade.

The front fork is an ADDSHOX 20‑inch oil‑spring suspension with 25mm of travel. Pair that with 2.4‑inch wide tires (front and rear), and pavement cracks, gravel roads, and grass all smooth out. You could even ride on hard‑packed sand (just avoid loose dry stuff).

6. Two Versions, Tailored to You

The saddle is PU with a backrest — wider, softer, with lumbar support. Long rides won’t wreck your lower back. Handlebars adjust way up or down, so you can ride upright and relaxed or slightly forward for a sportier feel. For senior riders, this is a dream: low step‑through, backrest saddle, three‑wheel stability, and a differential to prevent tipping. No wonder it’s called the best folding electric tricycle for seniors.

7. Hauling Made Easy — A True Pedal Assist Tricycle for Adults That Carries the Load

You don’t go out empty‑handed, right? The E-310 is a true beast of burden. With a total payload of 280 lbs for the rider plus an extra 80 lbs for the rear rack, you can haul a serious Costco haul or all your weekend fishing gear without breaking a sweat.

• Rear rack: 18" × 16" × 7.5" — up to 80 lbs
• Front basket: 13.5" × 10" × 5" — perfect for smaller essentials like snacks, a water bottle, or a light jacket

Use cases: Costco runs, weekend picnics, or carrying fishing gear. The heavy-duty rear basket frees your shoulders while you ride.

8. Details That Make the Difference

• KMC stainless steel chain: Rust‑resistant. Beach rides or rainy commutes won’t leave it stiff.
• Aluminum rims: Lighter than steel, no rust.
• Integrated lighting: Headlight and taillight run off the main battery. The taillight has a brake light function — squeeze the brakes and it glows brighter to alert traffic behind you. Night rides feel way safer.
• Parking brake: Stop on a hill, engage the parking brake, and the trike won’t budge. A lifesaver when loading cargo or getting on/off.

Addmotor offers free shipping to most urban areas within the 48 contiguous United States, with orders dispatched within 2 business days. California residents: this product includes a Proposition 65 warning — a legal requirement, nothing to worry about for normal use.
