Why does my Jorvik Tricycle make a grinding noise when the chain moves?
- K
  Karen ChristianSep 10, 2025
  If a grinding noise appears when the chain moves on your Jorvik Tricycle, the chain is likely dirty. If possible, remove the chains and clean them with a quality degreaser, agitating any dirt with a brush or chain cleaning machine. Inspect the chain for damage like twisted links or cracked plates and check for wear. Dry the chain, use a water disperser to remove residue, and apply a small amount of chain lubricant, wiping off the excess. Clean the cogs with degreaser and a rag, removing dirt from the cogs and hub/gear shifting assembly. Reinstall the chains and test. If you cannot remove the chains, use a small brush to clean them, though this may be less effective.

  Samantha BraunSep 8, 2025
  If the wheels on your Jorvik Bicycle aren't spinning freely, check that the front wheel is correctly seated in the dropout. If not, loosen the axle nuts with the front wheel on the ground, lift the fork slightly, and let it drop gently onto the wheel axle; then, tighten the nuts firmly with a 19mm socket or spanner. Also, check the front brake and adjust if it's applying too much pressure on the brake pads.

What to do if the handlebars move while riding Jorvik Bicycle?
- D
  Donald ScottAug 23, 2025
  If the handlebars move while you're riding your Jorvik Bicycle, it's likely that the securing nut is loose. Over time, the 5mm or 4mm hex bolts may loosen due to vibrations. Check that the 5mm bolts on the stem are tight. If your stem has face plates, ensure all 4mm hex bolts are tightened evenly.

- R
  Robert ElliottSep 5, 2025
  If the thumb lever on your Jorvik Bicycle isn't returning when released, it might be due to a sticky switch. Turn off the e-system. Using a contact cleaner spray or PTFE base spray lubricant, give a short squirt into the thumb lever assembly. Wait a few minutes and move the lever, flicking it to move the lubricant through the housing. Turn on the system and check if the thumb lever works.

What to do if when pressure is applied the chain becomes slack on Jorvik Bicycle?
- B
  Brian WattsSep 4, 2025
  If the chain on your Jorvik Bicycle becomes slack when pressure is applied, it's likely due to loose or worn fixings on the hub assembly or frame. Remove the nuts and hub guide plates (one may be yellow, the other brown) on the non-drive side of the hub axle. Check that they have a serrated surface; if they are smooth on the inside, replace them with new ones. Tension the chain and reassemble the parts onto the axle, then tighten.

  If the lights on your Jorvik Bicycle aren't coming on, it could be due to a loose connection or a blown LED. Follow the cable from the back of the lights to any connectors and ensure the connection is solid. Also, check the connectors at the back of the light. Look for any damage to the cables or light unit. Replace the unit if water or condensation is seen inside.

What to do if my tricycle got very wet and won’t turn on Jorvik JMT3 Bicycle?
- A
  Andrea MurphySep 2, 2025
  If your Jorvik Bicycle tricycle got very wet and won’t turn on, it's likely due to water in the connections or components. Unplug the battery and towel dry the outside. Spray contact cleaner or water disperser on the connection port. Leave it in a dry, warm place for 24 hours. Undo all connections, spray water disperser into each connection, and leave them unplugged. Towel dry all cables, plugs, and the tricycle itself. Store the tricycle in a dry area.

What to do if there is clunking from rear axle of Jorvik JMT3 Bicycle?
- P
  Paul HernandezSep 1, 2025
  If you hear clunking from the rear axle of your Jorvik Bicycle, the bearings may be worn or over-tightened. First, remove the wheels and tap the axle with a wooden mallet to reseat it in the bearings, then reinstall the wheel. If the issue persists after a length of time, the bearings may need replacing.

Why is there intermittent motor engagement on Jorvik Bicycle?
- M
  meganbrownAug 31, 2025
  The intermittent motor engagement on your Jorvik Bicycle is because the Bafang motor is intelligent and needs consistent pressure to engage. If your pedaling action isn't smooth and consistent, the motor might feel like it's turning on and off. Consistent pressure is required for smooth engagement.
