E-Moto Master Guide & FAQ

Fine silt and sand can get inside the throttle housing.

• Action: Carefully open the throttle housing and clean it with a dry cloth. Do not spray WD-40 inside the throttle, as it can interfere with the electronic hall-effect sensor. Keep it dry and clean.

The "All-Terrain" tires that come stock on many bikes struggle on wet leaves.

• The Upgrade: If you ride in deep mud, look for a Knobby Tire with wider spacing between the lugs. This allows the tire to "self-clean" (shed the mud) as it spins, giving you constant grip.

Mud is like liquid sandpaper. In autumn, your chain needs more frequent attention.

• Maintenance: Use a "Wet Lube" rather than a dry wax. Wet lubes are thicker and stay on the chain even when being pelted by rain and mud. Clean your chain immediately after a muddy ride to prevent surface rust from forming overnight.

Yes. Autumn humidity and mud can cause "micro-corrosion."

• The Fix: Unplug your main battery connector and any visible sensor plugs once a month. Apply a small amount of Dielectric Grease (Electrical Grease). This creates a waterproof seal and prevents "ghost errors" caused by moisture in the plugs.

Never use a high-pressure power washer directly on the electrical components (Controller, Battery, Display, or Throttle).

• The Safe Way: Use a low-pressure hose and a soft brush. For the motor and controller area, use a damp cloth.
• Pro-Tip: After washing, use a leaf blower or compressed air to blow water out of the electrical connectors and bolt heads to prevent corrosion.

Most high-quality e-motos (Surron, Talaria, 79Bike) are ratedIP67, meaning they arewater-resistant, not "submarine-proof." They handle rain and wet trails easily, but you should never submerge the motor or battery in deep river crossings.

• The Golden Rule: If the water is higher than the footpegs, turn back.

Heat makes brake fluid expand. If your brakes feel "sticky" or don't fully release, your fluid might be old or contaminated with moisture.

• Summer Maintenance: Ensure you are using high-boiling-point fluid (like DOT 5.1 or high-quality Mineral Oil depending on your model) to prevent "brake fade" on long downhill descents.

Yes. Hot air expands. If you set your PSI in a cool garage and then ride on hot asphalt or baking sand, your tire pressure will rise by 2–4 PSI.

• Action: Check your pressure at the riding location to ensure you still have the grip you need for the terrain.

Constant low-speed, high-torque situations (like technical rock crawling) create the most heat because there isn't enoughon-coming airflow.

• Pro-Tip: Ensure your cooling fins (on the controller) are free of dried mud and debris. If you ride in extreme heat frequently, consider adding an aftermarket Heat Sink or a specialized cooling fan kit.

Try to find shade. Direct sunlight on theblack battery casingandLCD displaycan cause temperatures to soar well above 50°C (122°F).

• The Risk: Extreme heat is the #1 killer of lithium battery capacity. If you must leave it in the sun, cover the seat and battery area with a light-coloured cloth or specialized bike cover.

Avoid this if possible.After a heavy trail session, your battery cells are internally hot. Charging adds even more heat.

• The 30-Minute Rule: Let the battery sit in a shaded, ventilated area for at least 30 minutes to "cool down" before plugging it into the charger. This significantly extends the long-term health of your lithium cells.

This is called Thermal Throttling. Your controller and motor have internal sensors. When they hit a specific temperature (usually around 80°C-90°C / 176°F-194°F), the system automatically reduces power to prevent permanent hardware damage.

• The Solution: If you feel a power drop, ride at a steady, low speed to allow airflow to cool the components, or take a 15-minute break in the shade.

Looks are deceiving. Tires lose roughly 1–2 PSI every month just from sitting. Riding on low pressure can cause a "pinch flat" or damage your rims on the first rock you hit.

• Action: Always re-inflate to your preferred PSI (usually 10–15 PSI for off-road, 25–30 PSI for street) before heading out.

Yes. Cold weather can affect the seals. Check the stanchions (the shiny inner tubes) of your forks for anyoil leaks. If you have air forks, check the PSI, as air naturally migrates out over time. A "dead" fork can make the bike feel unstable in corners.

Your chain is likely dry.

1. Clean it: Use a chain brush to remove any dust or surface rust.
2. Lube it: Apply a high-quality O-ring safe chain lube.
3. Check Tension: Ensure the chain hasn't slackened. Proper tension prevents the chain from jumping and damaging your motor casing.

Oxidation can build up on the rotors over winter.

• The Fix: Clean your rotors with specialized Brake Cleaner and a clean rag.
• The Check: If the lever feels soft, you may have air in the lines (especially with the mineral oil systems on Surrons). You might need a quick brake bleed to restore that "one-finger" stopping power.

If you followed our Winter Guide, your battery should be at ~50%.

1. Bring the battery to room temperature.
2. Give it a full 100% charge until the charger light turns green.
3. Leave it plugged in for an extra 1–2 hours once "full" to allow the BMS (Battery Management System) to balance the individual cells after their long hibernation.

Do not just turn it on and rip the throttle. Start with a Visual Inspection. Check for any rodent damage (mice love chewing on e-moto wiring harnesses) and ensure all bolts, especially the axle and subframe bolts, are still torqued to spec.

Wait! This is critical. Never charge a lithium battery if its internal temperature is below freezing (0°C/32°F). Charging a "frozen" battery causes "Lithium Plating," which can lead to an internal short circuit and fire.

• Rule of Thumb: Bring the battery inside and let it sit for at least 2 hours to reach room temperature before plugging it in.

No. Unlike old-fashioned lead-acid batteries, lithium batteries do not need a "trickle charger." In fact, leaving it plugged in for months can be a fire hazard and may damage the BMS (Battery Management System).

• Action Plan: Check the charge level once a month. If it drops below 30%, top it back up to 50% and then unplug it.

If your bike is stored in an unheated garage or shed,remove the batteryand bring it inside. Lithium batteries prefer "room temperature" (15°C–25°C / 60°F–77°F). Extreme cold can cause the internal resistance to spike, which degrades the battery's overall lifespan over time.

Never store your battery at 0% or 100% for long periods.

• The "Golden Zone": Store the battery at 40% to 60% charge.
• The Danger: Storing at 100% puts high osmotic pressure on the cells, while storing at 0% risks "deep discharge," which can permanently "brick" (kill) the battery so it won't charge again.

Yes! E-motos perform exceptionally well in cold, crisp air because the motor and controller stay cool. However, you will notice a 15-25% drop in range because cold temperatures slow down the chemical reactions inside the lithium cells.

• Pro-Tip: Keep the battery indoors until you are ready to ride. A "warm" battery performs significantly better than one that has been sitting in a freezing garage.

Electric drivetrains require significantly less maintenance than combustion engines. Key tasks include: checking tire pressure and brake pads monthly, inspecting suspension linkage every 3 months, cleaning the chain or belt drive after muddy rides, and updating firmware via the companion app when available. No oil changes required.
