    What’s New in Mini4 Pro

    Improved, Safer Battery Pack:

    Until now, all the Speedway Electric Scooters were fitted with a Lithium Polymer battery from a reputable Chinese manufacturer; however, from our experience with selling several hundred of Mini4s, it has been found that the battery defect rate averages about 8%, on an annualized basis—majority were out-of-box defects. There are some benefits of this technology, like a lower Wh/$$ cost & higher volumetric/weight densities.  

    In our continuous efforts to provide our Customers with the best possible purchase value, reduced downtime, & offer the greatest product longevity, we are extremely pleased to announce an agreement Speedway to fit a tried & tested LG Li-ion battery across the Speedway product line, including the Mini4, Speedway IV, & now with the introduction of the Speedway III as well. 

    The primary benefit to this LG Li-ion pack is that it’s predicted to yield a 20% improvement on degradation (based on manufacturer cell cycle data), improved safety, robustness, & can be repurposed at the end of the Scooter’s useful life. This pack is composed of the LG MH1 3.2Ah cell, configured as 13S4P—13 cells in series & 4 parallel—for a total of 52 cells in the battery pack. 

    Battery Lithium Ion vs Lithium Polymer

    Solid Front Rubber Tire:

    The most common problem on the Mini4, were getting flats on the front air Wheel. A sudden deflation, can be hazardous, loosing some ability to steer & maintaining control with the handlebar. As of June onwards, the Scooter is now fitted with a solid rubber tire, which is immune from punctures & flats. This upgrade will give you greater ease of mind while riding. Existing Mini4 Customers can purchase this tire as a replacement, it comes fitted in a new rim.

    Battery Lithium Ion vs Lithium Polymer

    Other Improvements:

    One other common problem that afflicted the earlier Mini4s, was a tendency for the screws to become loose & sometimes fall out. We have since directed the factory to start applying a threadlocker compound to the threads of screws during the assembly process.  

    Scooters are now shipped in a double box to reduce the chances of damage during transit. 

    What Makes The Speedway Mini4 Pro Unique?

    How Does It Compare?

    Control Features Functionality

    The Mini4’s Dashboard offers a concise easy to read layout of all the essential information you need for your journey, displaying: current speed, battery level, running time, odometer & the current power mode. Being backlit, it’s very readable while riding at night.

    Some of the configurable settings are:

    • Speed control
    • Start method selection: instant, or push off
    • Cruise-Control mode
    • Electronic brakes settings: sensitivity of the electronic brakes
    • Speed Display (Kilometer  Miles)

    Anatomy of the Speedway Mini4 Pro

    Background of the Speedway Mini4 Pro:

    Electric Kick Scooters have existed in some form or another for well over a decade. Until a relatively recently, the majority of these scooters were powered by extremely heavy Lead-acid batteries, which limited their range, power & usefulness. Advances in battery energy density, electronics & motor design are creating a quiet revolution with these kick scooter. At only 36lb, the Mini4 Pro provides an astonishing set of performance traits, that offer unrivalled balance of low weight, performance at the an unbeatable price.

    While electric scooters are beginning to gain traction in the US, in countries, like Korea, Speedway has been producing advanced state-of-the-art scooter designs for several years. For performance class scooters, there is really no serious large equivalent contender in this space, Speedway are unquestionable the market leader & have a solid reputation for quality & durability.

    The ‘Pro’ version is distinguished from the ‘LITE’ & ‘Standard’ edition in possessing the 500W hub motor vs. the 350W in the former two; higher 48V voltage vs. 36v in the other two & a large 614Wh battery pack. It is the best edition of the Mini4 you can purchase!

    The Importance of Suspension:

    Without suspension & a pneumatic air tire, using an Electric Scooter can be intolerably uncomfortable over long distances. The Speedway Mini 4 eases the pain through the use of adjustable dual shock dampeners (on the rear Wheel) & an articulated hinge that absorbs the impacts from the road’s imperfections.

    The front Wheel has an air tire, along with a shock absorber above the front fork. Combined, these features will give you one of the smoothest rides for an Electric Scooter you’ll be able to find on an Electric Scooter.

    The Optional Seat:

    An optional seat can be fitted onto the foot-board, allowing you to rest your legs for those long rides. All it takes to install is a regular screwdriver & requires about 1-2 minutes. The seat will be sold separately for $100.

    Frequently Asked Questions

    • I’ve been looking for an eScooter for several months. My requirements are that it should be powerful enough to go up some incliness, have a decent cruising speed, good range & not weigh to much, this looks perfect, are there any downsides to this model?
      If comparing to something like the Inmotion L8F, the Mini4 Pro weighs nearly 10lb more. Not everyone needs a scooter with a 38 miles range, which might be difficult for some people carrying up/down stairs. Finally, there is no Bluetooth function to connect to your cell phone for changing settings or viewing mileage stats.
    • What type of braking does the Mini4 have?
      The Mini4 is equipped with a drum-braking system. Of the three arresting technologies on a eScooter, each has it’s own benefits & drawbacks. The Mini4  uses a sophisticated combination of electrical regenerative braking, along with the mechanical drum brake. The advantage to this technology is that the wear-and-tear on the mechanical system is minimal, & not having to rely solely on the regenerative braking, means that there is less input power surging, which is detrimental to the longevity of the battery.
    • What is the Eco Mode? How does this work?
      The principle here is that the controller is supposed to smooth out the peaks in power, so that it can eek out slightly more range. In our testing, the difference with eco & standard modes is less than 5%. 
    • What are the recommendations to maximize the range?
      Operating at high speed consumes a lot more energy per mile than a more sedate 15MPH. The standard energy consumption rating is around 20Wh/mile at 15MPH, on flat terrain, with a 150lb Rider.  
    • How do the quick speed modes work—1-3 at the right side of the Dashboard?
      If set to 1, then the scooter is limited to around 9MPH, 2 = 15MPH, 3= Unrestricted. 
    • What type of warranty is there on the Mini4?
      We offer a one year warranty for the parts & labour. It does not include the shipping costs, which may be between $30-$105 (within the US), depending on the distance from our repair centre. While other dealers of Electric Scooters typically only offer a 3-6 warranty for the battery pack, we standby the products with one year.
    • Will you be offering spare parts? What spares will I expect to need over time?
      Yes, we have 40+ different parts, nearly everything needed to reconstruct a scooter from scratch. These will be posted onto the parts section of the website in the next month or so.
    • Is there a seat available for the Mini4? 
      Yes, the seat bolts into the foot platform & can be purchased separately for $100.
