ACTBEST Replacement Parts: Match the Model, Generation, and Part

To find the right ACTBEST replacement part, identify the exact bike and the component already fitted, then get the proposed replacement confirmed for that combination. A similar photo, matching plug, or shared model-family name isn't enough.

Start with your order record and the original part's visible markings. This guide helps you turn those details into a useful parts request, whether you're replacing a missing component or dealing with an older bike. It is not a cross-model compatibility list.

Identify the bike before identifying the replacement

Use the full model name from your purchase record, including generation and variant. Don't rename an older bike to match today's product listing.

For example, an old record identifying a Core ST or Core SO needs to stay identified that way until its generation is resolved. Our manuals page separately lists Core ST 2.0 and Core ST 2.0 Plus. Dropping those suffixes from a request loses information; the names themselves do not establish which parts interchange.

Gather this information before you shop:

If you bought the bike used, record what you know and mark the rest unknown. Don't substitute a guessed purchase year or claim an unmarked component is original.

Take a full-bike photograph, a view of the installed assembly, and a readable close-up of its label. Those views answer different questions: which bike it is, where the part sits, and what the part says.

Only photograph what you can reach safely. Don't open a housing or dismantle a suspect component to uncover a code. If you can't locate an identifier, describe that in the request. Keep order numbers, serials, addresses, and receipts in the private support channel.

Electrical and mechanical parts need different evidence

The best evidence depends on what you're replacing.

For a display, record a software or hardware version only if it is available through the matching manual's normal instructions. Don't alter hidden settings while searching. A display code describes what was shown, not which replacement part you should buy.

If a warning is the reason for the parts request, use our ACTBEST error-code support checklist to preserve the exact message and symptom timeline before asking which component, if any, needs replacing.

For mechanical parts, ask the installing technician to identify the relevant dimensions, interface, and specification. A tire size or clamp diameter may help narrow a search, but it doesn't answer every fit question. A steering or brake part that is damaged or insecure means the bike stays unridden until it is assessed.

A battery problem is not a normal parts-shopping step. For unusual heat, swelling, leakage, odor, odd noises from the pack, or smoke, stop use, get clear, and call 911 from a safe place. Don't charge it or approach the pack to unplug, move, or photograph it. The U.S. Fire Administration identifies these warning signs, and FDNY advises emergency escalation.

For an ordinary spare-battery inquiry with no warning signs, request confirmation of both the battery and its approved charger for your exact bike. Don't use voltage or connector appearance as the fit decision.

Our replacement-battery inquiry guide covers the extra pack-and-charger questions to settle before paying.

Send one useful request to ACTBEST

Email service@actbest.net, listed on our contact page, with the identity card and photographs. State whether you're asking about a possible warranty issue or purchasing a part. If you're unsure, describe the problem and ask for assessment.

The ACTBEST warranty policy requests purchase evidence and problem images for claims and provides an out-of-warranty parts contact. An inquiry doesn't confirm coverage or stock.

Use this private message:

Subject: Replacement part identification for [full model and generation]

Bike: [full model, variant, and known generation]
Purchase: [seller, date, and order reference, if available]
Serial: [number from the bike or record, or "not located"]
Shipping market: [country and state]
Original component: [name and all readable identifiers]
Problem: [what you observed and when it started]
Previous changes or shop findings: [details, or none known]
Attachments: [full bike, installed assembly, label, and affected area]

Please identify the correct replacement by part number or another specific designation and confirm its fit for this bike and configuration.

Is this eligible for warranty assessment, or should I purchase the part? What is the current price, availability, shipping cost, and applicable return policy? Who should install it, and does any claimed labor require approval before work begins?

If you need another identifier or photograph before confirming fit, please tell me exactly which one.

Don't diagnose the bike to make the message sound more technical. "The display stays blank when switched on" is a useful observation. "It needs a controller" is a conclusion unless a qualified diagnosis has established it.

If a shop has inspected the bike, attach its finding and identify it as the shop's assessment. That helps separate evidence from your own suspicion.

Check the reply before ordering or installing

Read the response against your identity card, not just the link to the suggested product. Mark each answer confirmed, not confirmed, or not applicable:

"Not applicable" is for a question that genuinely doesn't apply, such as paid purchase terms when a covered part is being supplied. An unanswered question remains not confirmed.

If the reply names a different generation, send the mismatch back before paying. If the part is unavailable, ask about an approved alternative and its identifier. Don't turn "out of stock" into permission to choose a lookalike.

Once you have a confirmed part, give the reply and instructions to the installer. When it arrives, check its label and supplied hardware against that confirmation before removing the old assembly. If something differs, pause installation and send photographs of the discrepancy. Don't splice a connector, enlarge a hole, or force a clamp to rescue the purchase.

You don't need to memorize a catalog. You need a clear match between the bike you own, the part you're ordering, and the person fitting it. Save that record with the receipt so the next repair starts with an identified component instead of another guess.
