I have a 72v 25ah battery in the back and my back up battery is a 52v 30ah battery. It's a great kit. With the 72v I am capable of going up to 53 mph for almost 30 miles. 45-53mph. For (29 miles) The 52v battery is 40mph for 30 miles. Thank you NBPOWER for building a good bicycle kit. Review: This kit is awesome! Exactly what I was looking for - The kit is an excellent fit for someone who wants to have a high top speed and get there fast! Be warned that the controller is 80A continuous so it will pull closer to 5-6,000watts! My 72v19.2ah battery gets very warm when I run the bike hard. But that is my fault for not buying the battery that the seller offered (I got the battery first and should have just paid the shipping to return it to buy theirs) Use the include torque arm and consider getting a second one. It has so much torque I almost spun it out of the dropout when I first installed it (Didnt make sure everything was tight enough) I hit a top speed of 55mph but I am almost certain that is a limitation of my battery. Get the highest quality tires you can find. I have a Schwalbe Super Moto-X on it and even then it is barely up to the task of this beast of a hubmotor! I would definitely recommend this kit to a friend and find the seller to be very easy to work with ## Features - Rear fork distance is 135mm - Sine wave Controller with controller bag - TFT UKC1 Color display - single speed freewheel - 48v-72v 3000w electric bike conversion kit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08R3TNCKT | | Additional Features | Aluminum Frame, Electric | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #333,321 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #270 in Cycling Electronics | | Bicycle Drivetrain Type | Single-speed | | Bicycle Gear Shifter Type | Twist Grip | | Bike Type | Electric Bike | | Brake Style | Linear Pull | | Brand | NB POWER | | Brand Name | NB POWER | | Color | 27.5inch Rear | | Customer Reviews | 4.2 out of 5 stars 27 Reviews | | Derailleur Configuration | Rear | | Electric Assist Type | Throttle and Pedal Assist | | Frame Material Type | Aluminum | | Gear Type | freewheel | | Included Components | Charger, Electric Bike | | Manufacturer | NB-YF-3KW | | Model Name | NB-YF-3KW | | Model Number | NB-YF-3KW | | Number Of Speeds | 1 | | Number of Handles | 2 | | Number of Speeds | 1 | | Power Source | electric | | Seat Material | Leather | | Size | 27.5 | | Suspension Type | Dual, Rear | | UPC | 749965183457 | | Warranty Type | Limited | | Wattage | 3000 watts | | Wheel Material | Aluminum | | Wheel Size | 27.5 inches | ## Product Details - **Age Range (Description):** Adult - **Bike Type:** Electric Bike - **Brand:** NB POWER - **Color:** 27.5inch Rear - **Frame Material:** Aluminum - **Included Components:** Charger, Electric Bike - **Number of Speeds:** 1 - **Special Feature:** Aluminum Frame, Electric - **Suspension Type:** Dual, Rear - **Wheel Size:** 27.5 Inches ## Images ![NBPOWER 135mm Dropout e-Bike Conversion Kit 48V-72V 3000W, 100km/h Speed, Alarm Lock - Image 1](https://m.media-amazon.com/images/I/51Yhj3wXxrL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Do the alarm on this controller lock the back wheel/hub motor when activated?** A: No **Q: Is there a soft start option for the motor?** A: If you change the speed control from 5 t0 9 settings you can control your take off so you wont end up in the bushes **Q: Does the tft ukc1 display have a usb port?** A: There is a USB port on the display **Q: Does anyone know the rim/wheel width where the tire bead goes of the 26” wheel kit?

You have to be able to think. Pros: When you get this product, you realize it's better than expected. This is a high performance product! Cons: There were no assembly instructions at all. Fortunately, I've been an aircraft mechanic 20 years, so I was able to install everything and even splice my old ebike throttle and brakes into this installation. It worked❗It was still a pain to figure everything out. The whole job took me about 6 hours (taking my time). Advice: be very careful when handling the controller wires (the power terminals) after connecting the battery, because it will shock you or spark even if you have disconnected the battery. Also, once everything is connected, you MUST turn on the display unit and go to system settings (double press "M"), and change the voltage to the voltage of your battery. My bike was sluggish at first, but after changing the settings, it was quick as fk. ## Frequently Bought Together - NBPOWER 135mm dropouts e-Bike kit 48V-72V 3000w e Bike Conversion Kit 100km/h Speed 3000W ebike Conversion kit(27.5inch Rear) - TIKSCIENCE Universal Torque Arm Conversion Kits for Electric Bicycle EBike Front or Rear Hub Motors 2 Sets, Electric Bicycle Maintenance Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/361081896-nbpower-135mm-dropout-e-bike-conversion-kit-48v-72v-3000w](https://www.desertcart.pt/products/361081896-nbpower-135mm-dropout-e-bike-conversion-kit-48v-72v-3000w) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-09*
