A complete motorcycle and sidecar combination, especially a vintage example with a matching, period-correct sidecar and transferable original registration, is a genuinely scarce find, and completeness, originality and whether the pairing is original to each other all drive value far more than with a solo motorcycle.
General vehicle sellers sometimes list a sidecar outfit simply as "vintage motorcycle and sidecar" without noting whether the registration is transferable or the pairing original, so a genuinely complete, matched combination can sit unrecognised inside an ordinary-looking listing.
Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. Search "motorcycle sidecar," a marque and model, or "sidecar combination" generally and results return across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.
Real results for "motorcycle sidecar": a genuine 1924 AJS model D 799cc sidevalve V-twin motorcycle and sidecar combination with transferable registration, found in one search.
It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.
Complete, correctly matched sidecar combinations don't come up often, so save a search (a marque, a period, or "motorcycle sidecar" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay, rather than relying on remembering to check each one.
The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching sidecar lots before adding the rest of the platforms via the extension.
Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and any applicable taxes included) is always in front of you.
