The short answer
Buying the right tire or tube is simple once you know your stock size — but on these bikes it's model-specific, and several ship in more than one wheel variant by region or trim. So two rules first:
- The sidewall of your current tire is the definitive answer. Read it before you buy.
- Match the tube to the tire size, and confirm your exact model and year — this reference is a cross-check, not a substitute for your sidewall.
With that said, here are the verified stock sizes by platform. Every size below is sourced to a manufacturer or vendor listing; where a value isn't reliably published, it's shown as — rather than guessed.
Sur-Ron
| Model | Front tire | Rear tire | Front / rear wheel |
|---|---|---|---|
| Light Bee X (2026 / 72V) | 70/100-19 | 3.00-18 | 19 / 18 in |
| Ultra Bee | 80/100-19 | 90/90-19 | 19 / 19 in |
| Storm Bee | 80/100-21 | 100/90-18 | 21 / 18 in |
| Hyper Bee (14/12 variant) | 60/100-14 | 70/100-12 | 14 / 12 in |
Notes: older 60V Light Bee models can differ from the 2026 sizes above — confirm your year. The Hyper Bee also ships in a 12/10 variant (60/100-12 front, 70/100-10 rear) — check which wheels yours has.
Talaria
| Model | Front tire | Rear tire | Front / rear wheel |
|---|---|---|---|
| Sting MX3 | 70/100-19 | 80/100-19 | 19 / 19 in |
| Sting R MX4 | 70/100-19 | 80/100-19 | 19 / 19 in |
| Sting MX5 Pro | 70/100-19 | 80/100-19 | 19 / 19 in |
| Komodo | 70/100-21 | 90/100-18 | 21 / 18 in |
| Dragon | 90/90-21 | 120/80-18 | 21 / 18 in |
Notes: the Sting MX3/MX4/MX5 share the 19/19 setup, but the larger Komodo (21/18) and Dragon (21/18) differ. Dragon specs vary by market/preproduction source — verify your exact trim.
Segway
| Model | Front tire | Rear tire | Front / rear wheel |
|---|---|---|---|
| X160 | 70/100-17 | 70/100-17 | 17 / 17 in |
| X260 | 70/100-19 | 70/100-19 | 19 / 19 in |
| Xaber 300 | 70/100-19 | 80/100-17 | 19 / 17 in |
Notes: Segway's support pages publish the X160 and X260 tires as a single tire type (same front and rear); the Xaber 300 runs a mixed 19/17 setup.
72V clones (Light Bee class)
| Model | Front tire | Rear tire | Front / rear wheel |
|---|---|---|---|
| E-Ride Pro SS3 (US) | 2.75-19 | 3.00-18 | 19 / 18 in |
| Rawrr Mantis X Pro | 70/100-19 | 2.75-17 | 19 / 17 in |
| Apollo RFN Ares (Rally) | 70/100-19 | 90/100-18 | 19 / 18 in |
| Arctic Leopard XF (US) | 70/100-17 | 90/100-14 | 17 / 14 in |
Notes — the variant traps here are real:
- E-Ride Pro SS3 ships as a 19/18 (US) and a 19/16 (UK) package (the UK runs 80/100-19 front, 90/100-16 rear) — confirm your market.
- Arctic Leopard naming overlaps: the US XF is 17/14, while the EU XF Pro R19 is a 19/16 bike (70/100-19 front, 70/100-16 rear). Confirm your exact model.
- RFN Ares has Rally / Endurance / Rally Pro trims — the tires above are the Rally; verify your trim.
These clones may share mechanical parts (see the compatibility guide), but tire sizes are model-specific.
Razor Dirt Rocket (kids)
| Model | Front tire | Rear tire | Front / rear wheel |
|---|---|---|---|
| MX350 | 12.5 x 2.75 in | 12.5 x 2.75 in | 12 / 12 in |
| MX650 | 16 x 2.4 in | 2.50-10 (most versions) | 16 / 14 in |
Notes: for the MX350, matching inner tubes are the 12.5 x 2.75 size. The MX650 rear is 2.50-10 on most versions, though a small number of early bikes used 3.00-9 — check yours. For the full Razor parts breakdown, see the Razor replacement guide.
About tubes
Where a bike runs a tubed tire, match the tube to the tire size above. A few verified examples: the 70/100-19 front tube fits the Light Bee X, Talaria Sting MX3/MX4, and Segway X260 (per a replacement-tube listing); the Razor tubes match their tire sizes above. For any bike where we don't list a verified tube size, match it to your tire's sidewall size and confirm with the seller.
The bottom line
Know your stock size and buying tires and tubes is easy — but on these bikes it's model-specific, several ship in regional wheel variants, and the clone family does not share one tire size. Use this table to know what to expect, always read your current tire's sidewall as the final word, and match the tube to that size. Keep the wheels healthy with the maintenance routine and the tire-change how-to, and if you're choosing a bike, run the Find Your Ride configurator.
VoltRipper is independent — we don't sell parts and our recommendations aren't pay-to-play. Sizes are verified against manufacturer and vendor sources and shown as "—" where not reliably published; they can vary by model year and regional variant, so always confirm against your exact bike's tire sidewall before purchase. Affiliate disclosure is included on monetized pages, and we're spec-verified/data-driven rather than hands-on until first-hand testing exists.
FAQ
What tire size does a Sur-Ron Light Bee X use?
The current 2026 (72V) Light Bee X uses a 70/100-19 front tire on a 19-inch front wheel and a 3.00-18 rear on an 18-inch rear wheel. Note that older 60V Light Bee models can differ, so confirm your model year — and the single most reliable check is always the size printed on your current tire's sidewall. The Ultra Bee, by contrast, runs different sizes (80/100-19 front, 90/90-19 rear on twin 19-inch wheels), which is one more reason never to assume 'it's a Sur-Ron' means one tire size.
What size tire does a Talaria Sting use?
The Talaria Sting MX3, R MX4, and MX5 Pro all use a 70/100-19 front and an 80/100-19 rear on twin 19-inch wheels. The larger Talaria models differ, though — the Komodo runs a 70/100-21 front and 90/100-18 rear (21/18 wheels), and the Dragon a 90/90-21 front and 120/80-18 rear. So confirm which Talaria you have before buying, and check your sidewall to be sure, because the lineup spans several wheel sizes.
How do I find the right tire or tube size for my bike?
Read the size printed on the sidewall of your current tire — that's the definitive answer, and it beats any chart because it accounts for your exact model, year, and any regional variant. Use a reference like this one to know what to expect and to cross-check, but the sidewall (and, for tubes, matching the tube to that tire size) is the final word. Several bikes in this class ship in more than one wheel variant by region or trim, so the sidewall check matters even more here than on a mainstream motorcycle.
Do all Sur-Ron and Talaria clones use the same tire size?
No — even within the 72V 'Light Bee-class' clones the sizes vary, so don't assume. Many run a 70/100-19 front (the Talaria Stings, Segway X260, Apollo RFN Ares), but rears differ: the Rawrr Mantis X Pro uses a 2.75-17 rear, the RFN Ares a 90/100-18, and the E-Ride Pro SS3 a 3.00-18 (US) — and some models ship in different regional wheel packages entirely. The mechanical parts may cross-fit across the clone family, but tire sizes are model-specific. Always confirm against your exact bike.
