{"product_id":"the-urban-current-20inch-e-bike-conversion-kit","title":"The Urban Current | 48V 1000W 20-Inch E-Bike Rear Conversion Kit","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eElectric mobility is not a trend. It is a reclamation of the street, a quiet revolution spinning on a hub motor and a lithium cell. The Urban Current is the instrument of that revolution — a 48V 1000W brushless rear hub motor engineered to transform any 20-inch bicycle into a legitimate electric vehicle, without the noise, without the fuel, and without the six-month waiting list of a factory e-bike.\u003c\/p\u003e\n\u003cp\u003eAt the heart of this kit is a toothed brushless motor that delivers 1000 watts of continuous power through a precision planetary gear reduction. The result is immediate, silent torque — the kind that flattens hills and shortens commutes without the whine of a direct-drive alternative. Paired with an intelligent sine-wave controller and an LCD display that reads speed, distance, and battery status in real time, this is not a hobbyist tinker-toy. It is a propulsion system with the voltage and current-headroom of a vehicle-class powertrain.\u003c\/p\u003e\n\u003cp\u003eThe conversion is surprisingly democratic: it bolts onto standard 20-inch rear dropouts, accepts both V-brake and disc-brake configurations, and arrives with every connector, torque arm, and throttle needed to complete a weekend installation. The motor housing is sealed against road spray. The wiring harness is color-coded and keyed. This is a system designed by people who understand that a stranded rider at 10 PM is the enemy of every good product decision.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eYou do not need a new bike.

It is equally at home on the 5-mile office commute, the weekend errand loop, or the campus-to-dorm run. Fleet operators and food-delivery riders will appreciate the low operating cost and field-serviceable design — swap a controller or throttle in minutes without specialized tools.

The kit is designed for a 48V lithium battery pack (Li-ion or LiFePO4) with a discharge current rating of at least 25A continuous. We recommend a capacity of 10Ah or higher for practical range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this fit my bicycle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The motor is built into a 20-inch rim and fits standard 20-inch rear dropouts with an OLD (over-locknut distance) of approximately 135mm.
