Key Features
Description
We designed the X-PRO Milos 50 for adult and teen riders who need a street-legal 50cc gas moped for daily commuting, campus transportation, and short-trip errands โ and want the most complete feature package in the under-$900 50cc category without paying for add-ons separately. The Milos 50 runs a 49.6cc 4-stroke air-cooled GY6 engine through a CVT automatic transmission: no clutch, no gear shifting. It is EPA certified and DOT approved for street-legal use in 48 U.S. states. At $869.95, it arrives with a lockable rear trunk already in the box, 10-inch aluminum alloy wheels, an LED headlight, and USB + Type-C dual charging ports โ none of which require a separate purchase.
The lockable rear trunk is the most practical differentiator in this price category. Most competing 50cc mopeds at this price either don't include a trunk or charge extra for it. The Milos 50 ships with the trunk in the box โ mount it on the rear rack and use it from day one for a helmet, grocery bag, or daily essentials. The 7 color options (Black, Blue, Red, Green, Orange, Pink, White) are the widest range available for any 50cc gas scooter under $900, including Pink, Green, and Orange that most competing brands don't offer at this price.
The USB + Type-C dual charging ports are confirmed standard equipment based on buyer reviews โ charge your phone while riding for navigation or communication. The 10-inch aluminum alloy wheels are lighter and stronger than the steel rims used on lower-priced competitors. The CVT automatic means no clutch and no gear shifts โ twist the throttle and ride, making the Milos 50 accessible to first-time riders and daily commuters who prefer simplicity.
The Senlong GY6 (139QMB) 49.6cc 4-stroke engine is the world's most produced scooter platform. Nearly every motorcycle shop in America has serviced a GY6; parts are available locally and online. Top speed is 35+ MPH depending on rider weight and road conditions โ suited for city streets and neighborhood commuting. A front disc brake and rear drum brake provide dependable stopping, and a kill switch provides emergency cutoff. The dual-start system pairs electric push-button ignition with an independent kick-start backup so a drained 12V battery never strands you.
The Milos 50 is EPA certified and DOT approved for street-legal operation in 48 U.S. states. IMPORTANT: This vehicle is NOT CARB certified โ it cannot be legally sold, titled, registered, or operated in California. In most U.S. states, a 50cc scooter below a defined speed threshold can be operated with a standard driver's license โ no motorcycle endorsement required โ but requirements vary by state. Always check with your local DMV for 50cc license and registration requirements before riding on public roads. Top speed of 35+ MPH makes this vehicle suited for city streets and neighborhood roads, not sustained highway use.
X-PRO has operated in the U.S. powersports market for over 20 years as a licensed motorcycle dealer. When you buy the Milos 50, you are buying from a dealer with two company-owned warehouses in California and Texas, a dedicated U.S.-based support team, and full OEM replacement parts stocked before the vehicle goes on sale. Frame warranty: 1 year. Parts and battery warranty: 90 days. A basic tool kit is included in the box. Assembly video is available on YouTube โ search 'Xpro MC-Y001 YB50QT-3 Milos 50 Installation'.

Why Buy From Us
Company History
The company behind X-Pro has been operating in the U.S. motorcycle and powersports market for over 20 years. We are a licensed U.S. motorcycle dealer โ not a dropshipper or a temporary marketplace seller. Our operations include product sourcing, compliance review, warehousing, fulfillment, after-sales support, and a dedicated parts inventory, all managed in-house from the United States.
The X-Pro Brand
X-Pro was established in 2018 as a dedicated powersports brand, built on over two decades of hands-on experience in the U.S. market. The product line includes mopeds, scooters, dirt bikes, motorcycles, ATVs, go-karts, and electric powersports vehicles โ all sold with full dealer backing. X-Pro was built to bridge the gap between anonymous marketplace sellers with no support and premium-priced established brands.
Why Riders and Families Choose X-Pro
For some buyers, X-Pro is a practical first bike โ a more manageable way to start riding without overcommitting on cost. For others, it is a way to get back into powersports without the repair anxiety that comes with premium machines. For parents, X-Pro is often the answer to: how do you give your child the experience of riding without spending several thousand dollars? X-Pro makes that practical, backed by the same parts availability and warranty support that come with every unit we sell. Always ensure the vehicle's speed rating, size, and weight capacity are appropriate for the rider's age, size, and experience level.
Warehouses & Fulfillment
We operate two company-owned warehouses โ one in California and one in Texas. These are not third-party logistics (3PL) facilities; they are staffed and managed by our own team. Inventory is stored, quality-checked, and shipped directly from these locations, giving us control over packaging, inspection, and delivery timelines across the continental United States.
After-Sales & Warranty
Every complete unit is backed by a manufacturer warranty. Warranty claims and support requests are handled by our U.S.-based team with direct access to inventory systems, warehouse operations, and product records to resolve issues efficiently.
Parts Availability
We maintain a full replacement parts inventory at our U.S. warehouses. Parts are stocked before vehicles are listed โ not ordered from overseas after a customer reports an issue. Parts orders ship from the same facilities that handle complete units.
Warranty
Assembly & Setup
What's in the Box
Vehicle body (85% assembled), front wheel (1), front fender (1), front panel (1), handlebar clamp bolts (1 set), rear rack (1), rearview mirrors (1 pair), battery (12V/7Ah, 1), battery cover (1), rear trunk (1, lockable), tool kit (1), owner's manual (1). NOTE: Helmet is NOT included โ required for safe riding, sold separately.
What to Assemble
Front wheel (Intermediate โ mount to front fork, align brake disc, tighten axle nut) ยท Front fender (Basic) ยท Handlebar clamp bolts (Basic) ยท Front panel (Basic) ยท Rear rack (Basic) ยท Rearview mirrors ร2 (Basic) ยท Battery (Basic โ Red [+] first, then Black [โ]) ยท Battery cover (Basic) ยท Rear trunk (Intermediate โ set on rear rack, fasten securely). โ ๏ธ After assembly, IMMEDIATELY test speedometer and odometer โ known issue reported by multiple buyers. If either does not function, check the speedometer sensor cable at the front wheel hub connector and contact support if issue persists.
Assembly Time
Approximately 45โ60 minutes with basic hand tools. Two-person assembly recommended. Front wheel installation is intermediate difficulty โ refer to the included owner's manual and the assembly video on YouTube (search: 'Xpro MC-Y001 YB50QT-3 Milos 50 Installation').
Before You Buy
1 ยท Stay Connected โ We Need to Reach You
After your order ships, our team will contact you by phone and email to coordinate delivery. Answer calls from unfamiliar numbers โ our team and your carrier may call from numbers you don't recognize. Check your email daily, including your spam folder, until your vehicle arrives. Without a valid, reachable contact number, your carrier cannot complete delivery. If we cannot reach you, your order may be returned at your expense.
2 ยท Shipping & Delivery โ LTL Freight
Your vehicle ships via LTL (Less-than-Truckload) freight from our U.S. warehouse. The carrier will contact you to schedule a delivery appointment โ make sure your contact information is current. Large freight trucks cannot enter narrow roads or tight residential areas. You must meet the driver at an accessible point, or arrange terminal pickup if needed. Inspect the vehicle carefully before signing the delivery receipt. If damage is found, note it on the receipt and contact us within 24 hours with photos.
3 ยท Assembly & Setup
Professional mechanic assembly is highly recommended. Improper DIY assembly voids safety guarantees and can lead to mechanical failure โ incorrect assembly is one of the leading causes of early issues with new vehicles. Regardless of who assembles it, you must tighten all bolts and apply thread-locker (Loctite) before the first ride. Vibration will loosen factory settings during use, causing parts to fall off or break. This is a required pre-ride step, not a defect. A basic tool kit is included in the box.
4 ยท Engine Maintenance โ Gas Models
Change the engine oil before your first ride โ factory fill is a break-in oil not suitable for extended use. Skipping this step is the leading cause of engine seizure on new vehicles. Use fresh 87+ octane fuel only. Do not use high-pressure washers near engine or electrical components. Drain fuel for long-term storage. Store in a dry area.
5 ยท Real-World Performance
Top speed and power output are measured under optimal lab conditions. Actual performance varies based on rider weight, terrain type, road conditions, and ambient temperature. Fuel quality also affects performance โ always use 87+ octane fresh gasoline. Riders above 180 lb may notice a reduction in top speed on hills. Do not expect maximum rated performance in all real-world riding conditions.
6 ยท Storage
For long-term storage (30 days or more), drain the fuel tank and run the carburetor dry โ do not store with old fuel as it will gum the carburetor and jets. Disconnect the 12V starter battery if storing for more than 60 days to prevent discharge. Store the vehicle indoors in a dry, temperature-stable environment, covered to protect from dust. Before returning to service after extended storage, inspect all bolts, tire pressure, brake function, and battery charge level.
7 ยท Safety & Rider Requirements
This vehicle is designed for riders age 16 and older. In most U.S. states, a standard driver's license is sufficient to operate a 50cc scooter โ no motorcycle endorsement required โ but requirements vary by state; always check your local DMV before riding on public roads. IMPORTANT: This vehicle is NOT CARB certified and cannot be legally sold, titled, registered, or operated in California. Always wear a properly fitted, approved helmet and appropriate protective gear โ helmet is not included. Maximum total load capacity (rider + cargo) is 225 lb โ do not exceed. Top speed of 35+ MPH makes this vehicle suitable for city streets and neighborhood roads, not sustained highway use.
8 ยท Break-in Period
We recommend a break-in period for the first 3โ5 hours of riding. During this period, avoid sustained full-throttle operation and vary your speed to allow the engine and drivetrain components to seat properly. After break-in, perform an oil change and re-inspect and re-tighten all bolts. A properly completed break-in reduces early wear and extends the vehicle's service life.

Why Buy From Us
Company History
The company behind X-Pro has been operating in the U.S. motorcycle and powersports market for over 20 years. We are a licensed U.S. motorcycle dealer โ not a dropshipper or a temporary marketplace seller. Our operations include product sourcing, compliance review, warehousing, fulfillment, after-sales support, and a dedicated parts inventory, all managed in-house from the United States.
The X-Pro Brand
X-Pro was established in 2018 as a dedicated powersports brand, built on over two decades of hands-on experience in the U.S. market. The product line includes mopeds, scooters, dirt bikes, motorcycles, ATVs, go-karts, and electric powersports vehicles โ all sold with full dealer backing. X-Pro was built to bridge the gap between anonymous marketplace sellers with no support and premium-priced established brands.
Why Riders and Families Choose X-Pro
For some buyers, X-Pro is a practical first bike โ a more manageable way to start riding without overcommitting on cost. For others, it is a way to get back into powersports without the repair anxiety that comes with premium machines. For parents, X-Pro is often the answer to: how do you give your child the experience of riding without spending several thousand dollars? X-Pro makes that practical, backed by the same parts availability and warranty support that come with every unit we sell. Always ensure the vehicle's speed rating, size, and weight capacity are appropriate for the rider's age, size, and experience level.
Warehouses & Fulfillment
We operate two company-owned warehouses โ one in California and one in Texas. These are not third-party logistics (3PL) facilities; they are staffed and managed by our own team. Inventory is stored, quality-checked, and shipped directly from these locations, giving us control over packaging, inspection, and delivery timelines across the continental United States.
After-Sales & Warranty
Every complete unit is backed by a manufacturer warranty. Warranty claims and support requests are handled by our U.S.-based team with direct access to inventory systems, warehouse operations, and product records to resolve issues efficiently.
Parts Availability
We maintain a full replacement parts inventory at our U.S. warehouses. Parts are stocked before vehicles are listed โ not ordered from overseas after a customer reports an issue. Parts orders ship from the same facilities that handle complete units.

Before You Buy
1 ยท Stay Connected โ We Need to Reach You
After your order ships, our team will contact you by phone and email to coordinate delivery. Answer calls from unfamiliar numbers โ our team and your carrier may call from numbers you don't recognize. Check your email daily, including your spam folder, until your vehicle arrives. Without a valid, reachable contact number, your carrier cannot complete delivery. If we cannot reach you, your order may be returned at your expense.
2 ยท Shipping & Delivery โ LTL Freight
Your vehicle ships via LTL (Less-than-Truckload) freight from our U.S. warehouse. The carrier will contact you to schedule a delivery appointment โ make sure your contact information is current. Large freight trucks cannot enter narrow roads or tight residential areas. You must meet the driver at an accessible point, or arrange terminal pickup if needed. Inspect the vehicle carefully before signing the delivery receipt. If damage is found, note it on the receipt and contact us within 24 hours with photos.
3 ยท Assembly & Setup
Professional mechanic assembly is highly recommended. Improper DIY assembly voids safety guarantees and can lead to mechanical failure โ incorrect assembly is one of the leading causes of early issues with new vehicles. Regardless of who assembles it, you must tighten all bolts and apply thread-locker (Loctite) before the first ride. Vibration will loosen factory settings during use, causing parts to fall off or break. This is a required pre-ride step, not a defect. A basic tool kit is included in the box.
4 ยท Engine Maintenance โ Gas Models
Change the engine oil before your first ride โ factory fill is a break-in oil not suitable for extended use. Skipping this step is the leading cause of engine seizure on new vehicles. Use fresh 87+ octane fuel only. Do not use high-pressure washers near engine or electrical components. Drain fuel for long-term storage. Store in a dry area.
5 ยท Real-World Performance
Top speed and power output are measured under optimal lab conditions. Actual performance varies based on rider weight, terrain type, road conditions, and ambient temperature. Fuel quality also affects performance โ always use 87+ octane fresh gasoline. Riders above 180 lb may notice a reduction in top speed on hills. Do not expect maximum rated performance in all real-world riding conditions.
6 ยท Storage
For long-term storage (30 days or more), drain the fuel tank and run the carburetor dry โ do not store with old fuel as it will gum the carburetor and jets. Disconnect the 12V starter battery if storing for more than 60 days to prevent discharge. Store the vehicle indoors in a dry, temperature-stable environment, covered to protect from dust. Before returning to service after extended storage, inspect all bolts, tire pressure, brake function, and battery charge level.
7 ยท Safety & Rider Requirements
This vehicle is designed for riders age 16 and older. In most U.S. states, a standard driver's license is sufficient to operate a 50cc scooter โ no motorcycle endorsement required โ but requirements vary by state; always check your local DMV before riding on public roads. IMPORTANT: This vehicle is NOT CARB certified and cannot be legally sold, titled, registered, or operated in California. Always wear a properly fitted, approved helmet and appropriate protective gear โ helmet is not included. Maximum total load capacity (rider + cargo) is 225 lb โ do not exceed. Top speed of 35+ MPH makes this vehicle suitable for city streets and neighborhood roads, not sustained highway use.
8 ยท Break-in Period
We recommend a break-in period for the first 3โ5 hours of riding. During this period, avoid sustained full-throttle operation and vary your speed to allow the engine and drivetrain components to seat properly. After break-in, perform an oil change and re-inspect and re-tighten all bolts. A properly completed break-in reduces early wear and extends the vehicle's service life.
