Overview

The ST50 is the step-through counterpart to ENVO's 50 Series D50. The published foundation is the same torque-sensing rear-drive platform: 48V 15Ah LG battery, 500W Class 2 / 750W Class 3 statement, 80 Nm (59 lb-ft) maximum torque, 9-speed drivetrain, hydraulic brakes and 80 mm lockable fork. Its key advantage is access: the lower frame opening makes stop-and-go city riding, cargo loading and remounting less awkward.

Best For

The ST50 suits a rider who wants the D50's 50 Series capability but values a more accessible mount and dismount. That can matter on delivery stops, rides with a rear rack or basket, or for anyone whose knee, hip or flexibility makes a high top tube unpleasant. Choose the D50 instead if you simply prefer a high-step frame. Choose the U50 if child or cargo platform capacity is the primary job.

Performance

ENVO publishes 500W Class 2 and 750W Class 3 settings, 80 Nm (59 lb-ft) maximum torque and 20 or 28 mph (32 or 45 km/h) speed statements. The torque sensor uses pedal input to scale assistance more smoothly than a basic cadence-only system. The 28 mph (45 km/h) figure is capability, not universal legal access. Confirm the bike's delivered setting, your state's class rules and the rules for the particular path or road.

Battery

The ST50 uses ENVO's published 48V 15Ah LG lithium battery with CAN battery and charger communication. ENVO claims a maximum of 93 miles (150 km), under favorable conditions. For normal planning, reserve margin for hills, cargo, stop-start riding, wind, cold and higher assistance. Charge using the supplied compatible charger in a dry, attended location. Terrain sets your real range: flat commutes in Chicago, Dallas, and Minneapolis reach the top of the claim, while hill routes in Seattle, San Francisco, or Pittsburgh land near the bottom.

Safety & Certification

ENVO describes an ISO 4210 and EN 15194-engineered frame, Tektro hydraulic disc brakes, integrated lights and an 80 mm adjustable lockable fork. It does not publish a model-specific U.S. UL 2849 system statement on the current page, so StreetRides does not make one. Before riding, verify brake feel, tire pressure, battery lock, controls, lights and the frame's fit. Use a helmet and follow local speed and access requirements.

Assembly, Service & Ownership

The ST50's current page lists a Bluetooth-capable display, Shimano Alivio 9-speed drivetrain, lockable fork and hydraulic brakes. Finish assembly carefully and run a low-speed brake-and-shift check before loading cargo or using higher assistance. StreetRides' return and shipping policies apply to this purchase. Retain the order record should manufacturer warranty support be needed.

Specifications

Published ST50 data: 500W Class 2 / 750W Class 3 geared rear motor. 80 Nm (59 lb-ft) maximum torque. 20 or 28 mph (32 or 45 km/h) speed statements. 48V 15Ah LG battery with CAN. Up to 93 miles (150 km) claimed range. 62 lb (28 kg) bike weight. 441 lb (200 kg) payload. Small and large step-through sizes. Shimano Alivio 9-speed drivetrain. 80 mm adjustable lockable fork. Tektro hydraulic disc brakes. Integrated lighting and Bluetooth display. No package shipping weight is stated.

Honest Verdict

The ST50 is the practical choice inside the D50/ST50 pair when mounting ease is part of the ride experience, not an afterthought. It keeps the torque-sensing 50 Series hardware and 400 lb published payload while avoiding a high-step frame. It is still a 62 lb-class bike, its maximum range is conditional, and its Class 3 statement needs a location-specific rule check.

KEY ADVANTAGES

Why This Ride Stands Out

Step-through 50 Series frame

The lower frame opening is the functional reason to choose ST50 over the high-step D50.

80 Nm (59 lb-ft) torque-sensor assistance

Published 500W Class 2 / 750W Class 3 settings respond to pedal pressure for smoother starts.

400 lb payload and hydraulic brakes

ENVO's 441 lb (200 kg) payload claim includes rider plus cargo. Hydraulic brakes deserve a proper setup check before loading it.

StreetRides takeaway

Choose by riding surface, frame access, carry/load needs and evidence confidence, not just by the biggest advertised range figure.

Its range figure is a maximum claim, and Class 3 capability deserves a local-rule check before it becomes a buying decision.

It may fit a rider looking for a 50 Series commute-and-cargo bike with torque sensing and a 400 lb published payload figure. Buyers who need unambiguous source documentation today should compare the D50 high-step and ST50 step-through pages, whose model identities are clearer. A 50 Series torque-sensor e-bike with a documentation gap: ENVO publishes the 48V 15Ah, 80 Nm (59 lb-ft) and 750W claims, but parts of the X50 page name ST50. Think twice if: The X50 has usable published 50 Series credentials, but the page's ST50 naming leakage is too material to ignore. That does not make the product fictitious. It means the honest listing treats its shared-platform evidence as provisional where model-specific details could differ. Buy it only after the frame and component configuration is confirmed if that distinction affects fit, accessories or price. View product details

Frequently Asked Questions

The pages distinguish 20 mph Class 2 and 28 mph Class 3 capability. The delivered configuration and the rule for the exact road, lane or path determine what is lawful.

48V 15Ah LG lithium battery with CAN communication and ENVO's up-to-93-mile (150 km) maximum range claim. Treat the maximum range as a favorable-condition figure, not a trip guarantee. Load, terrain, wind, weather and speed change it.

It is total payload. ENVO's published number includes you, your accessories, and your cargo, not cargo on top of a rider limit.

No model-specific U.S. whole-bike UL 2849 system claim is published on the current page. ISO/EN frame language is not the same thing.

Confirm fit and assembly, then inspect tire pressure, fasteners, brakes, steering, lights and battery latch before a low-speed first ride.
