Question 1

the deck and handlebars got really dirty, can i just wipe it down with a wet towel or what?

Accepted Answer

DIAGNOSIS The deck is vulcanized rubber and the handles are silicone. Both can be cleaned, but moisture must be kept away from electronic junctions. FIX Use a cloth dampened with water and a mild soap. Wring it out so it is damp, not wet. Wipe down the rubber deck, stem, and handlebar grips. Immediately dry all surfaces with a separate, clean, dry microfiber cloth. Do not spray or pour liquid directly onto the scooter. IF THAT DIDN'T WORK For stubborn stains on the deck, use a dedicated rubber cleaner or isopropyl alcohol (70%) on a cloth. Test on a small area first. Avoid all-purpose cleaners or solvents which can degrade the rubber and silicone. HEADS UP Never submerge any part of the scooter. Avoid getting moisture in the charging port, around the power button, or at the base of the stem where wires pass through. Water ingress there can cause controller failure and is not covered under warranty.

Question 2

the charger light stays green even when i first plug it into the dead scooter, it's not charging.

Accepted Answer

DIAGNOSIS This indicates no communication between the charger and the scooter's battery management system (BMS). The circuit is open. FIX Unplug the charger from the wall and the scooter. Inspect the magnetic charging port on the scooter for bent pins, debris, or corrosion. Inspect the charger's magnetic plug for the same. Reconnect firmly, ensuring a solid magnetic connection. Plug into the wall. The light should turn red if contact is made. IF THAT DIDN'T WORK Test the charger output. With nothing connected, plug it into the wall. A green light confirms the charger has power. Use a multimeter on the DC pins of the magnetic plug. You should read approximately 42V. No voltage means a failed charger. HEADS UP Only use the official Unagi magnetic charger. Third-party chargers with the same plug may not initiate the handshake with the BMS and will not charge, potentially locking the battery system.

Question 3

the folding mechanism is super stiff and i'm scared i'm gonna break it trying to lock it.

Accepted Answer

DIAGNOSIS The stainless steel latch pins and the receiver holes are likely dry or have accumulated fine dust/debris, increasing friction. FIX Fold the scooter to the unlocked, open position. Apply one drop of light machine oil (like 3-in-1 oil) to each of the two silver latch pins on the stem. Also apply a drop to the hinge joint. Work the mechanism open and closed 10-15 times to distribute the lubricant. Wipe away any excess. IF THAT DIDN'T WORK Inspect the black plastic locking cam inside the latch mechanism for cracks or deformation. Operate the latch lever while watching the cam rotate. If it does not move smoothly or appears damaged, the latch assembly needs replacement. HEADS UP Never force the latch closed. The correct sequence is: fold stem down, press the silver button on the latch, then push the latch lever forward until it clicks. Forcing it can shear the plastic cam.

Question 4

my scooter suddenly brakes by itself for a second or feels like it's surging, not smooth.

Accepted Answer

DIAGNOSIS This is the electronic regenerative braking system engaging inconsistently, often due to a faulty throttle sensor or connection. FIX Power the scooter off. Visually inspect the throttle assembly on the right handlebar. Check for any visible damage or looseness. Gently rotate the throttle through its full range, feeling for a 'dead spot' or gritty resistance. Clean around the throttle with a dry cloth to remove moisture or debris. IF THAT DIDN'T WORK The issue may be in the motor controller. Perform a reset. Turn the scooter on. Simultaneously press and hold the power button and the mode button for 10 seconds until the scooter powers off and back on. This reboots the controller. HEADS UP This surging can be more pronounced when the battery is above 90% charge, as the regen system has limited capacity to put energy back into a full battery. It is a known quirk of the system.

Question 5

the range on my e500 is way less than advertised, like 5 miles on a full charge in mode 2.

Accepted Answer

DIAGNOSIS This is typically due to a combination of rider weight, terrain, and tire pressure. The advertised range is under ideal lab conditions. FIX Check and adjust tire pressure first. Use a gauge. Inflate both tires to the maximum 50 PSI printed on the tire sidewall. Higher pressure reduces rolling resistance. Use Speed Mode 1 for maximum range. Avoid constant full-throttle acceleration and hills. IF THAT DIDN'T WORK The battery may have degraded. Fully charge the scooter until the charger light is solid green. Note the estimated range shown in the Unagi app. If it shows significantly less than ~12 miles for a new battery, the battery capacity has diminished. HEADS UP Rider weight over 180 lbs will drastically reduce range. The dual-motor E500 model consumes battery nearly twice as fast as the single-motor E250, especially in Mode 3. For range, use a single motor if your model allows it via the app.

Question 6

how do i pair my unagi with the app? it never shows up in my phone's bluetooth list.

Accepted Answer

DIAGNOSIS The scooter's Bluetooth module is not in discovery mode. It only broadcasts its signal under specific conditions. FIX First, turn the scooter on. The power light must be solid white. Open the Unagi app. Go to the 'Add Scooter' screen. Only then, press and hold the Mode button (the one that cycles speed settings) for 5 seconds until the power LED blinks blue. The scooter should now appear in the app's list as 'Unagi-XXXX'. IF THAT DIDN'T WORK Ensure no other Bluetooth device is actively connected to the scooter (like an old phone). Turn Bluetooth off and on on your phone. Force quit and reopen the Unagi app. Repeat the pairing sequence with the scooter within 3 feet of your phone. HEADS UP The scooter will not appear in your phone's general system Bluetooth menu. Pairing must be initiated and completed only through the Unagi app interface.

Question 7

the scooter makes a loud clicking or grinding noise from the front wheel when i accelerate, feels rough.

Accepted Answer

DIAGNOSIS This is almost always a foreign object lodged in the gear drive of the front motor. The Model One uses a geared hub motor, not direct drive. FIX Turn the scooter off. Tilt it back. Manually spin the front wheel and inspect the gap between the wheel rim and the motor housing. Use a flashlight. Remove any visible debris (pebble, stick, wire) with tweezers or a thin tool. Spin the wheel again to confirm noise is gone. IF THAT DIDN'T WORK The noise may indicate internal gear damage. Check for lateral play in the front wheel by gripping the tire and trying to wiggle it side-to-side. Any significant movement points to a bearing or gear failure requiring service. HEADS UP Do not hose down or pressure wash the wheel. Water forced into the motor housing can wash lubricant from the gears and cause this failure. Clean only with a damp cloth.

Question 8

my unagi e500 just beeps twice and won't turn on, the power button lights up red for a second then nothing.

Accepted Answer

DIAGNOSIS This is the low battery protection circuit activating. The battery voltage is below the safe operating threshold for the BMS. FIX Connect the official Unagi charger to the scooter. Confirm the charger light is red. Leave it to charge undisturbed for a minimum of 30 minutes. Attempt to power on. If successful, continue charging to full (charger light turns green). IF THAT DIDN'T WORK The issue may be a poor charger connection. Unplug everything. Firmly reseat the charger cable into the scooter's charging port. Ensure the magnetic connector is clean and fully seated. Listen for a faint click. Retry the charging process. HEADS UP Do not attempt to ride or repeatedly press the power button during the initial 30-minute charge. This can draw the battery down further and trigger a deep protection lockout requiring a longer, full-cycle charge to reset.
