Off-Road E-Bike Wholesale: S60 vs H26 vs S18 Spec Guide
An off road e bike wholesale spec guide for distributors comparing 1000 W fat-tire models S60, H26 and S18, and the rows on the sheet that decide whether a unit sells.
WHY THIS GUIDE
If you are building an off road e bike wholesale line for a distributor catalog or a dealer floor, you already know the trap: three 1000 W fat-tire models from the same supplier can look interchangeable on a one-page PDF and behave very differently once they reach your customer. This guide walks through what to read on the spec sheet when the headline wattage, battery voltage, and top speed are nearly identical. The reference models are S60, H26, and S18 from the CaddyTrail / Shenhaiyuan (Dongguan) Intelligent Technology Co., Ltd. e-bike line, with the higher-output S8 mentioned for context. Always confirm the figures below against the latest product page before you place a purchase order.
WHAT A FAT-TIRE OFF-ROAD E-BIKE IS ACTUALLY SELLING
Same motor class, different ride character
S60, H26, and S18 all run a 1000 W motor on a 48 V 15 Ah battery pack. On a glance that reads as the same headline. In practice the three frames are aimed at slightly different riders: S60 is the 20-inch fat-tire platform with 4.0-inch wide tires, H26 is the 26-inch wheel format with wide off-road tires, and S18 is the 20-inch full-suspension step-through. Each one is sold as an off road e bike, and each one suits a different buying motive on your dealer's floor.
Who the end customer actually is
For a fat-tire e-bike wholesale order, the end customer is rarely the same across the three SKUs. S60 attracts the rider who wants the 20-inch balloon-tire feel with a 47 kg net weight and a 150 kg load rating. H26 fits a buyer who wants 26-inch wheel rolling speed on mixed surfaces, with a lighter 38 kg net weight and a 120 kg load rating. S18 fits the rider who wants 20-inch wheels, front and rear dual suspension, and a 44 kg net weight at a 150 kg load rating. Picking the right mix means deciding which customer you actually want to walk through your dealer's door.
READ THE SPEC SHEET FOR WHAT IT DOES NOT PRINT
Tire size and load rating
Tire size is where a fat-tire e-bike supplier typically differentiates the line. S60 ships with 20-inch wheels and 4.0-inch wide fat tires. H26 ships with 26-inch wheels and wide off-road tires for all-weather grip. S18 also ships with 20-inch wheels. Confirm the load rating in kilograms, not just the pressure number, if your market includes heavier riders or cargo use. S60 and S18 are rated at 150 kg, which gives more headroom for a 100 kg rider carrying groceries than the 120 kg rating on H26, and the two numbers live on different lines of the spec sheet.
Brake system and rotor size
S60 uses front and rear hydraulic disc brakes. H26 uses front and rear hydraulic dual disc brakes. S18 lists mechanical or hydraulic disc brakes on the product page, so the configuration you ship is part of the order spec rather than a fixed line item. The headline reads as similar across all three, but ask the supplier for the rotor diameter in millimeters and whether the calipers are two-piston or single-piston for the SKU you actually order. A photo of the brake assembly for your specific configuration is worth more than a single word on the spec table.
Suspension and frame weight
S18 is built around front and rear dual suspension with a 44 kg net weight. H26 lists a high-strength steel frame with front and rear suspension and a 38 kg net weight. S60 uses a high-strength steel welded frame. Net weight is one of the easiest figures to confirm during a video factory walk, and it is the spec your dealer staff will be asked about when a customer is comparing two units side by side.
RANGE, SPEED, AND BATTERY: SAME NUMBERS, DIFFERENT QUESTIONS
Treat published range as a reference, not a guarantee
S60 and S18 are rated at 80 km to 100 km per charge under nominal conditions. H26 is described as offering stable, lasting range for commutes and weekend rides without a published kilometer figure. Actual range depends on rider weight, terrain, assist level, ambient temperature, and tire pressure. Treat any 80 km to 100 km line as a usable ceiling on flat ground with light assist, not as a guarantee your customer will hit on a hill day. Battery longevity over time depends on use patterns and charging habits, so the curve for any individual pack is something to ask about rather than assume.
Top speed and what it means in your market
S60 is listed at up to 50 km/h. H26 lists 45 km/h to 50 km/h. S18 lists 40 km/h to 50 km/h. The 1000 W motor class sits above the EPAC 25 km/h ceiling that EN 15194 covers, since EN 15194 applies to 250 W pedal-assist bicycles rather than to 1000 W throttle-capable units. In the United States, e-bike road access is set at the state level and class-based, with class 1 and class 2 capped at 20 mph and class 3 at 28 mph. Before you ship an off road e bike wholesale line, confirm the road-legal classification for each destination with your regulatory advisor. We will not speculate on a per-market legal verdict here; that conversation belongs to your compliance team working with ours.
CERTIFICATION: MODEL BY MODEL, NOT BY CATALOG
S60 and S18 are listed against CE and FCC standards
The S60 product page references CE, FCC and other international certifications. The S18 product page states the unit is certified to CE and FCC standards. Treat both lines as your starting point for shipping into the EU and North America, and request the underlying certificate file before you commit a container, since standards revisions and destination-specific add-ons can change the picture between catalog versions.
H26 sits on international certification support
The H26 product page uses the phrase international certification support and notes that the model meets multiple international quality certifications with supporting documentation, which is less specific than the CE and FCC line on S60 and S18. For a fat-tire e-bike wholesale program that includes H26, the practical question is which destination certificates the model actually carries and which ones our team can help you align. Ask for the specific certificate list before you lock the SKU into a market-specific shipment. We will line up the documentation per shipment rather than guess the scope.
Confirm per shipment, not per brochure
A manufacturer-level compliance statement covers the catalog, not each SKU in each destination. Our position is that each model and each shipment destination has its own paper trail, and the right place to confirm scope is our dealer team with the destination and target SKU in front of them. For markets that require UL, EN 15194 alignment, or local registration, the same conversation applies. Send us the model and the destination, and we will confirm what is on file and what would need to be added.
WHERE S8 FITS IN THE LINE
S8 is the higher-output sibling
S8 runs a 2000 W motor on a 48 V 20 Ah pack with a 40 km/h to 50 km/h top speed, a 150 kg load rating, disc brakes front and rear, and a high-strength steel frame. It is not in the same 1000 W comparison set as S60, H26, and S18, but it is the right answer when a dealer asks for a higher-power, higher-load unit in the same catalog. Stocking S8 alongside the 1000 W trio gives the dealer a step-up SKU without leaving the CaddyTrail line.
VETTING A FAT-TIRE E-BIKE SUPPLIER BEFORE YOU SIGN
Production scale and patent base
Ask for the daily production figure at the factory level. Shenhaiyuan (Dongguan) Intelligent Technology Co., Ltd. runs a 5,000+ unit daily capacity with 30+ technical patents and shipments into 30+ countries. That scale absorbs a mid-volume fat-tire e-bike supplier program without missing your seasonal window, and the patent base signals that the e-bike line is the manufacturer's own engineering work.
Direct-from-factory pricing model
CaddyTrail is set up as a Factory Direct Supplier serving distributors, brands, and golf courses worldwide. For an off road e bike wholesale order that means pricing is quoted on the factory side, with the OEM / ODM conversation open if you want your own brand on the frame, the battery pack, or the controller firmware. Ask how private-label artwork is handled, what the minimum order quantity is per colorway, and how the after-sales parts pipeline is structured before you commit a program.
Parts and warranty pipeline
The warranty conversation on a fat-tire 1000 W line usually comes back to the battery pack, the controller, and the brake components. Ask the supplier which parts ship from stock on a 30-day turnaround, which need a custom production slot, and how warranty claims are routed back to the factory. A clear answer to that question tends to be a stronger signal than any brochure image.
PUTTING THE THREE SPEC SHEETS SIDE BY SIDE
Read across the rows, not down the columns
When you line up S60, H26, and S18 on a single comparison sheet, the motor, battery, and top-speed rows are nearly identical. The rows that actually differentiate the three SKUs are wheel size and tire format, suspension travel, net weight and load rating, brake specification, and the certification status of each individual model. Read the sheet across those rows before you read down the headline numbers. That is the difference between a fat-tire line that sells to three different customer types and three SKUs that cannibalize each other on the dealer's floor.
