Ok, we are REALLY excited about this. Biktrix Electric Bikes, founded in 2014 with successful Kickstarter and Indiegogocampaigns, had again raised the bar in the electric mountain bike (e-MTB) category. They have recently introduced one of the best electric mountain bikes on the market today in the US.

Presenting to you the most awaited full suspension bike of 2018 - the Juggernaut Ultra FS. Equipped with top of the line components and the most powerful torque sensor mid-motor in the industry (1000W rated, 1500W peak), this bike easily specs out as the best built full suspension ebike in the industry today.

The Biktrix Juggernaut Ultra full-suspension electric mountain bike offers a range of propulsion methods, so you will never hesitate in your hill climbing. First, it features a 48V, 1000W Ultra mid-drive motor by 8Fun (Bafang), which has 5 levels of pedal assist. There is a convenient class 2 thumb throttle, which allows you to power the bike without pedaling. And there is a SRAM Gx 10-speed drivetrain, which let's you control your pedaling power with precision.

And with Tektro Auriga hydraulic disc brakes from and rear (180mm rotors), and brake-triggered motor cutoffs, you will also have great stopping power. Brake cables are stainless steel with BK casings, 

One bike instead of 3 bikes!

2018 Ultra bikes is equipped with the latest version of the Ultra motor with metal reduction gears. Biktrix is the first company to bring Ultra bikes to production in the world. With our first batch of bikes already sold and user tested, we have more experience with these bikes than anyone else.

These bikes have been built with a lot of care and attention. They put 4 years of experience building Juggernaut bikes to bring these to you.

By the way, did you know that "Ba" in Mandarin means 8 and the dialect of Mandarin renders "fun" as fang..!! So when you see 8Fun and Bafang, know that they are referring to the same awesome company.

About The Bafang Ultra Mid Drive Motor

The new Bafang Ultra mid-drive motor is one of the most powerful mid drive motors on the market. With 1000 watts of power and 160 Newton meters of torque, this is an electric bike that can easily maintain speeds of 28 mph and climb the steepest hills with ease.

Like the Bafang Max drive system, the new Bafang Ultra motors constantly sample relevant information at a frequency of up to 80k Hz via a torque sensor and two speed sensors which are all highly sensitive. The resulting data on crank torque, vehicle speed and the speed of rotation of the pedals is made available to the controller, ensuring precise control of the vehicle while achieving the highest possible efficiency.

The Ultra Max Drive System puts the rider in complete control. In spite of a generous power output and a maximum torque of more than 160 N.m, the motor operates in virtual silence.

    shipping and return policy

    Order Confirmation

    As soon as you place an order you will receive an order confirmation email. The email include details about the order, and is your record that we have received your order in our system and pre-authorized your credit card for the purchase.

    Before we contact the warehouse to confirm that the selected item(s) are in stock and available for immediate shipment, all orders are subject to fraud protection analysis. This protects both ourselves and the customer, by ensuring that credit cards are not being used fraudulently, and no ID theft has occurred. This process can take anywhere from a few minutes to a few hours. Upon fraud clearance, the supplier is contacted to fulfill the order.

    The time between placing and order and having it shipped can vary from one day to several weeks. Some products are readily available and can ship almost immediately after an order is placed. Some suppliers, on the other hand, build products to order, so upon notification that an order has been received, they will assemble the product and ship it, usually 7-10 days (but sometimes longer).

    If a product cannot ship within 48 hours of the order being placed, we will contact the customer to let them know what fulfillment timeframes to expect. If a product is on backorder, estimated shipping times are subject to several variables, including delays at border crossings.

    If your item is on backorder or unavailable, we will reach out to you by email or phone, and see if you want to keep the order and wait for the product to come back into stock; cancel the order; and/or change it for a different item or items. If you cancel your order, we will void the pre-authorization and your item(s) are. If available for immediate shipment, we will process the charge and submit the order for shipment.

    Order Shipment

    If your order is in stock and we process the charge to your credit card, it will ship within typically within 24-48 hours from the date of your order. We will send you tracking information within 24 hours of your order leaving the warehouse to the email address you provided at checkout. Please know that some suppliers will take up to a week to fulfill an order, but we work diligently with each one of them to shorten shipping times on every order. 

    If you do not receive tracking information, feel free to follow up with us at: or by phone (toll free 888-883-3350).

    All products are shipped via UPS, FedEx (or similar shipping companies), and may require signature for delivery. IF YOUR PACKAGE APPEARS DAMAGED FROM SHIPPING, DO NOT ACCEPT IT. TAKE PHOTOGRAPHS OF THE DAMAGED BOX, TELL THE DRIVER THAT YOU CANNOT ACCEPT DAMAGED GOODS, AND NOTIFY US IMMEDIATELY. If you accept a package that appears damaged from shipping, it will be much more difficult to process a return. It is advisable to photograph the unboxing, or even record a video of the unboxing and assembly process, thereby qualifying you for a Cash Back Reward of $100.

    Warranty Claims

    We work diligently with our customers to avoid warranty claims, and will seek to resolve issues amicably. Bicycles and scooters require initial assembly, adjustments and fittings, and regular maintenance thereafter, and none of these requirements are covered by manufacturer warranty. If fact, the inverse is true: failure on the part of the customer to properly maintain their new bike could result in voiding a warranty.

    All warranty communication is ultimately between the customer and the manufacturer for genuine issues of workmanship or defect within the warranty period, and the supplier will repair or exchange products AT THEIR DISCRETION.

    REALLY GOOD EBIKES AND ITS SUPPLIERS DO NOT TYPICALLY ACCEPT PRODUCT RETURNS DUE TO BUYER REMORSE. THEREFORE, BEFORE PLACING YOUR ORDER, PLEASE MAKE SURE THAT THE PRODUCT(S) YOU CHOOSE WILL MEET YOUR NEEDS WITHOUT REGRET. If the customer has not opened or used the item, and it can still be sold as new, the item may to be returned to the supplier (upon their prior approval) and Really Goods LLC will refund the customer once the supplier determines the salability of the item, and has processed their own corresponding wholesale refund.

    Cancellations & Refunds

    All sales are final. At the discretion of Seller, orders cancelled after 24 hours may be subject to a 38% administration fee, whether or not your order has shipped. If your order has shipped, you (the Buyer) will also be responsible for actual return shipping charges. REFUNDS WILL ONLY  BE ISSUED TO THE ORIGINAL PAYMENT METHOD USED WHEN PLACING THE ORDER. RETURNS AND REFUNDS ARE SUBJECT TO POLICIES OF THE RESPECTIVE BRAND SUPPLIER. Brands such as EWheels will accept unopened returns, but the customer will bear the cost of the original shipping, return shipping, and a restocking fee. So please, before placing your order, make sure this is a product you want and will not regret purchasing. Seller may cancel orders at their discretion.

    The electric bikes we sell come mostly assembled, and many customers are fine completing the assembly process, which typically involves attaching the front wheel, attaching and adjusting the handlebar, attaching pedals, adjusting the brakes, and checking to make sure all the connections are secure and fit to the riders height and desired riding position.

    But for those who what this done for them, we now offer free professional bike assembly with every ebike sold. How does this work? Well, you can contact us and we'll find a local shop to do the assembly for you, or you can simply include your local bike shop as the shipping address when you check out. Make sure to include an "order note" when checking out, so that we can do all the coordination for you.

    Some restrictions apply. You will need to live close enough to a local shop where your bike can be assembled for you. The local shop will need to offer assembly services - but this is a very common service, and we have never called a shop that wouldn't do this for around $50. If it costs more than that, you will need to pay the difference. Once the work is completed, just email us a copy of the store receipt, and we'll refund you $50.

    Not sure if this is for real? Call us now and we'll show you how it works. Call us toll free at 888-883-3350. Or send us an email to

    Please note that this amazing offer cannot be combined with our otherwise incredible discount codes.
