Product Overview

The ZUMIBIKE ZUMI-RT01 750W 48V 20Ah retro fat tire electric bike is a purpose-built retro-style electric bicycle for B2B distribution in the US and EU markets. It combines a 750W rear hub motor, 48V 20Ah lithium battery, and 20" x 4.0 fat tires on a 6061 aluminum alloy frame — this moped-style electric bike delivers the torque, range, and retro aesthetic that lifestyle-oriented riders demand. ZUMIBIKE ships from in-region warehouses in the US, EU, and Brazil, with delivery of 3–7 business days from stock.

Core Technical Specifications

Motor, Battery, and Market Configuration

Contrary to what most spec comparisons suggest, a 750W motor rating does not deliver the same performance in every market. Local road regulations cap assisted speed and can classify higher-wattage motors as mopeds requiring registration. The ZUMIBIKE ZUMI-RT01 750W 48V 20Ah retro fat tire electric bike solves this by offering dual-configuration support: 45 km/h for US market builds, and a compliant 25 km/h for EU builds. One SKU covers both regulatory environments, simplifying inventory management for multi-market distributors.

The 48V 20Ah battery provides 40–80 km range per charge. For retail communications, the 40 km conservative figure reduces post-purchase range disappointment — a known pain point in the e-bike category. The rear hub motor uses Bafang components, providing procurement-stage supplier credibility beyond the wattage number.

Fat Tire Performance and All-Season Usability

The 20" x 4.0 fat tire specification has a functional purpose beyond the retro styling. In cities where cobblestone streets and mixed-surface paths are common, the wider contact patch delivers stability that standard commuter tires cannot match — making this a practical advantage for all-season riders across Northern Europe, Pacific Northwest markets, and regions with variable surface conditions. Product imagery confirms the bike as all-season and US warehouse ready.

It is not the lightest retro e-bike available, and fat tires add rolling resistance on smooth pavement. That said, for buyers targeting year-round riders or crossover customers who split time between paved roads and light trails — including markets with an active e bike mountain bike culture — this trade-off delivers broader addressable demand than a narrow-tire commuter alone. Hydraulic disc brakes provide consistent wet-weather stopping performance at any speed.

Compliance and Import Cost Structure

For B2B buyers importing a 48V 20Ah electric bike into the EU or North America, compliance documentation determines whether a shipment clears customs on schedule. A common pitfall at EU customs clearance is discovering that the CE Declaration of Conformity referenced component standards not applicable to the shipped configuration. Before placing an order for the ZUMIBIKE ZUMI-RT01 750W 48V 20Ah retro fat tire electric bike, confirm that the supplier's documentation covers CE, EN15194, FCC, UL2849, and UL2271 for the specific configuration ordered.

ZUMIBIKE holds EU white-list manufacturer status, reducing anti-dumping duty rates to as low as 19.2% for bicycles and 33.4% for electric bikes. For distributors managing tight landed-cost models, this delivers measurable margin recovery on volume orders. For North American buyers, US Section 301 tariff structures on Chinese-made electric bikes affect total landed cost beyond . The US warehouse in-region stock provides an import-cleared fulfillment option for buyers managing tight delivery windows.

Manufacturing Capability

ZUMIBIKE operates a 20,000 m² facility in Hangzhou with 50+ engineers, 300,000 units annual production capacity, and 100+ quality inspection nodes per unit. The Zhejiang manufacturing base provides access to a mature e-bike component ecosystem for efficient production cycles and component sourcing. Over 200 patents support design differentiation and compliance documentation. For buyers conducting remote supplier evaluation, these are verifiable capability signals. Supply capacity of 5,000 units per month supports seasonal replenishment at volume.

Application Scenarios

Urban Commuting

The retro moped-style aesthetic and 750W torque delivery make the ZUMIBIKE ZUMI-RT01 750W 48V 20Ah retro fat tire electric bike a credible daily commuter. The 40–80 km range covers most urban commute profiles without mid-day charging. For dealers in markets with e bike mountain bike crossover demand, the fat tire configuration extends the bike's appeal beyond pure commuters.

All-Season and Recreational Use

Fat tires and hydraulic disc brakes extend seasonal usability into wet and cold conditions. UL2849 and UL2271 certifications address battery and electrical safety concerns that have become visible purchase criteria in high-density urban markets. EU warehouse stock with 2–7 day delivery supports just-in-time retail restocking.

Fleet and Private-Label Distribution

MOQ of one unit enables low-risk trial orders. The Standard 7-speed drivetrain provides a maintainable component standard with accessible spares for fleet operations. ZUMIBIKE's OEM and ODM options allow brand owners to customize colorways and graphics for private-label deployment without a separate manufacturing relationship.
