If an e-bike develops a problem, start by describing what happens. A noise, a changing brake feel or a display error is more useful to a mechanic than guessing which part needs replacing.
This guide explains the basic observations owners can make and when to use a workshop or contact the seller.
Stop if a safety-critical part seems wrong
Do not keep riding to test a problem with brakes, steering, wheel security, the frame or a damaged battery. Arrange an inspection before using the bike again.
For a battery that is swollen, leaking, unusually hot or making unusual sounds or smells, stop using and charging it. Do not open the pack. Follow Fire Rescue Victoria's battery safety guidance; if there is smoke or fire, move to safety and call 000.
If the bike will not turn on
Read the startup steps in your model's manual. Without dismantling anything, check whether the battery appears charged, seated and locked as instructed. Note any display light, error code or sound.
Do not bridge terminals, bypass a lock or use an unapproved charger to experiment. Send the observations to the seller or technician. Several faults can produce the same symptom.
If the motor assistance feels different
Note when it happens: starting, climbing, coasting or after the bike warms up. Record the assistance setting, displayed battery level and any error message. Mention recent transport, rain, servicing or changes to accessories.
Do not change hidden controller settings as a repair. If assistance becomes unpredictable, stop and ask for assessment.
If the brakes rub or feel weak
Check whether a wheel or brake part appears loose, damaged or out of position. Keep fingers away from moving rotors. If braking is reduced, a lever changes suddenly or fluid is leaking, do not ride.
A workshop can check pad and rotor wear, alignment and the hydraulic system. Keep lubricants and cleaning sprays away from brake pads and rotors. Do not treat brake noise with general oil.
If you have a puncture or wheel problem
Read the tyre marking and use the correct replacement tube or tyre. A rear motor wheel has electrical connections and model-specific removal steps, so use the manual or a workshop familiar with the bike.
Stop for a loose axle, broken spoke, damaged rim or tyre that will not stay seated. A recurring pressure loss also needs checking instead of repeated inflation alone.
Can a regular bike shop help?
Many bicycle workshops can service mechanical parts such as tyres, chains and brakes. Electrical diagnosis depends on the shop's tools, training and access to the relevant parts and information.
Before booking, give the model and generation. Ask which work the shop can do, the inspection cost and whether you will receive a quote before extra work starts. Ask whether to bring the battery, charger, keys and invoice.
Contact the seller before a possible warranty repair
If you expect a repair to be covered, contact the seller before authorising third-party work. DiroDi's warranty process requires written approval for outside repairs submitted for reimbursement. Statutory consumer rights remain separate.
Send your order number, model, purchase date, a description of the problem and useful photos. Keep the conversation and approvals together. Read the warranty guide for the process.
Keep repairs and maintenance separate
Tyres, brake pads and chains wear with use. A regular inspection helps identify that wear before a breakdown. Record service dates, work performed and parts replaced.
Use our maintenance checklist for routine care. For help finding the next step for a DiroDi, contact our Melbourne support team.
