Eclio Terrn 2 Pro

Overview

The Eclio Terrn 2 Pro is built for a very specific type of rider. Eclio officially classifies this as an off-road e-bike, but its performance numbers speak to something far closer to a lightweight dirt bike. Instead of the typical 500W to 750W motor you find on modern commuter e-bikes, this model houses a massive 2500W motor capable of pushing out 135 Nm of off-the-line torque.

Priced at $2,599, it lands in a competitive middle ground for high-speed electric mobility. Visually, the frame mimics a dirt bike chassis with a massive center battery block taking the place of a traditional gas tank. It is shipped ready for street-legal riding with full lighting and signals, but its soul is strictly built for massive acceleration and off-road thrills.

Real-World Performance

Acceleration on the Eclio Terrn 2 Pro is incredibly aggressive. Once you touch the throttle, the bike wants to leap forward, easily hitting 28 mph in less than half a city block. If you unlock the top speed settings via the display, pedal assist level 5 will absolutely haul. During straight flat-ground testing, the bike clocked 14 mph in gear one, scaled up to 37 mph in gear four, and ultimately topped out at an impressive 46 mph.

Hill climbing and extreme range tests proved just as formidable. Pointed up a steep 20% grade hill on level 5, the bike held a steady 17 mph all the way over the crest, which is outstanding for a single-motor bike of this weight. To test the battery limits, Mike rode a brutal 1.5-hour, throttle-only route. The bike managed 20.38 miles while climbing 1,650 feet of elevation, maintaining a high average speed of 26 mph. Even with just one battery bar left, the top speed only dropped slightly to 26 mph and retained much of its initial punch.

Braking and pedaling response are a bit of a mixed bag due to the bike's sheer mass and cadence sensor limits. From a standstill, it takes about 1.5 full pedal revolutions for the motor to deliver its massive boost of power. If you are already riding at 20 mph, that delay stretches to about 2.5 revolutions. However, braking is quite reliable; the bike managed a full stop from 37 mph in exactly 50 feet.

Design & Build Quality

The most noticeable aspect of the Terrn 2 Pro's design is the weight. At 127 lbs, it weighs almost double that of a standard e-bike. This extra mass drastically changes the handling dynamics. While you can still rip turns quickly, it takes noticeably more physical effort at the wide handlebars to maneuver the bike. Fortunately, riding no-handed remains surprisingly stable.

Off-road capability is well supported by the suspension and tire choice, though it requires some tuning. The front features a plush motorcycle-style fork, while the rear utilizes a coil shock. Out of the box, the rear suspension is set too soft and bottoms out easily over bumps, so tightening it is highly recommended before hitting the trails. The aggressively treaded tires excel in loose conditions, gripping flawlessly through 2 to 3 inches of soft gravel.

Build quality has a few weak points. The motor sings quite loudly at top speeds, and the massive battery enclosure has a noticeable rattle when tearing down unpaved trails. However, rider comfort is a plus. The seat is very soft, keeping fatigue at bay even after an hour-long, 13-mile stretch.

Key Features

The electronics package brings both welcome tech and a few frustrating compromises. The bike uses an NFC card system or a digital passcode for security, keeping unauthorized riders from activating the motor. The massive 60V 32Ah battery block is fully removable with a key, though it does require a lengthy 6 to 8 hours to fully recharge.

Street legal features include a headlight, horn, brake-activated tail light, and turn signals. Unfortunately, the handlebar controls for these features utilize cheap plastics that feel completely out of place on a $2,600 machine. The basic 7-speed Shimano shifter also feels stripped off a budget entry-level bicycle. Furthermore, the turn signals offer no auditory click or visual dashboard indicator, meaning you have to manually ensure the switch returns to neutral to avoid driving with a blinking light.

Who It's For

The Eclio Terrn 2 Pro is firmly aimed at adrenaline junkies and power-hungry riders who want dirt bike speeds without dealing with gas. If you plan to ride fast in bike lanes, conquer steep off-road climbs, and rely almost entirely on the throttle rather than your legs, this is a phenomenal option.

Who Should Skip It

Commuters looking for a traditional bicycle experience or who need to carry their ride up flights of stairs should not buy this. At 127 lbs with a delayed cadence sensor, it is much too heavy and cumbersome for riders who want natural pedal assistance or nimble city weaving.

How It Stacks Up

Compared to the broader e-bike market, the Terrn 2 Pro simply exists in a different weight class. A standard commuter e-bike runs a 48V 15Ah to 20Ah battery with a 750W motor pushing 75 Nm of torque. By nearly doubling the battery voltage and tripling the motor wattage, the Eclio trades the lightness and agility of traditional e-bikes for raw, undeniable motorcycle-grade acceleration.

Final Verdict

For $2,599, the Eclio Terrn 2 Pro delivers incredible thrills and power that easily conquer steep hills and rough gravel trails. While the plastic accessories and rear suspension setup leave a bit to be desired out of the box, its raw acceleration and 46 mph top speed make it a standout hybrid for off-road electric enthusiasts. The bike comes with a 2-year warranty and a 30-day trial period.
