Frequently Asked Questions
Why two wheels in front?
In short, the two front wheels give you stability and control in soft sand, mud, snow and other off-road conditions. For a full explanation, please click here.
I’m tall. How tall can you be and still ride Rungu?
Rungu offers options for riders up to 6’8” (203 cm) and taller. For riders taller than 6’3” (190 cm), we recommend steering risers and saddle upgrades. Learn more on our post – “Rungu Height and Posture Guide”
I’m short. How short can you be and still ride Rungu?
Rungu has a very low stand over height (26.5 in.), and it can accommodate individuals who are 5' (152 cm). Learn more on our post – “Rungu Height and Posture Guide”
How heavy is Rungu?
With three wheels instead of two, Rungu is heavier than a single-front-wheel E-Bike (extra front wheel and extra fork).

How much weight can I tow with Rungu Dualie?
Rungu Dualie® has so much torque it can tow a truck! But for practical purposes, Rungu Dualie's tow limit is 300 lbs. (136 kg) – trailer and cargo. The Rungu Cargo Rack has an optional ball hitch that makes it easy to attach a deer cart or hitch-compatible trailer. If you don't want the Cargo Rack or want to use the Cargo rack for other purposes, Rungu offers the Rungu Deer Cart and Rungu Cargo Trailer. Both hook up to the Rungu Dualie with or without the Cargo Rack.
How much weight will a Rungu support?
We design Rungu frames to support up to 350 lbs - combined weight of the rider and cargo. Models that include the Rungu Cargo Rack support less because of the weight of the cargo rack and in some cases the additional battery.
The Cargo Rack can support up to 180 lbs. of weight evenly distributed on the upper surface, so maxing out the Cargo Rack leads to a maximum rider weight of 170 lbs. To determine how much weight you can put on the rack and ride safely, select the maximum load for a model with a Cargo Rack (Rungu Dualie Steep, Rugged or Dualie XR) and subtract your weight.
For example, if I weigh 185 lbs. If I’m riding the Dualie Steep, I subtract my weight from the max load of the Dualie Steep (347 lbs.). That leaves 161 lbs. for cargo load on the rack.

What’s the range for the Rungu Dualie or Dualie XR?
The rough answer - 20 miles per battery (40 miles for Rungu Dualie XR models), but it can be less or much, much more...
Range varies dramatically depending on terrain, loaded weight and road surface. The Rungu Dualie is designed and intended for off-road use, so we quote ranges on dirt roads in two ways – at optimum speed, motor-power only (with no power input from pedaling) and with pedal assist. In the case of pedal assist, we assume the same rider on the same terrain at the same speed but contributing 50W of power (about what you need to maintain 10-15 mph on level road/asphalt on a normal 2-wheel bike). For the sake of reference and comparison to other E-Bikes, we now also show the estimated range on pavement on level ground.
To see range specifications by model, click here: Rungu Dualie Features and Specifications
Range is affected by hills, rider weight, head wind, tire pressure, speed and stopping/starting. Rungu makes estimates based on the weight of each MDV model with a 175 lb. (79 kg) rider. These estimates assume zero headwind, low steady speed (no stopping and starting), ideal tire pressure and a flat or rolling riding surface. The estimated pavement range is the optimized calculation. For difficult off-road conditions such as deep snow, mud or soft sand, range can be significantly shorter. In practical experience, Rungu riders have achieved ranges exceeding 100 miles for the Rungu Dualie XR Steep on rolling terrain a variety of surfaces with stopping, starting, hill climbs and descents, off-road and on paved trails.
Does Rungu Dualie come with a throttle?
The standard Rungu Dualie configuration (off-road only) has a thumb throttle to control the motor. If you order your Rungu Dualie to be configured as a Class 1 e-bike, the factory removes the throttle prior to shipment. Class 1 e-bike motors can only be activated using pedal assist (PAS). For more information about E-Bike classes and Rungu, contact sales@rungudualie.com.
Can I ride Rungu Dualie in sub-zero winter conditions?
Yes. Rungu uses Li-Ion batteries that operate with predictable range down to -20 degrees Centigrade ( -4 degrees Fahrenheit). Batteries continue to operate below the temperature specifications, but the impact on range is not well understood. At -20 degrees Centigrade, range decreases by 10% to 17%. To learn the three rules about battery management in winter, read our blog post on the subject.
How can I carry a Rungu on my vehicle?
We recommend the Rungu Dualie Hitch Rack v2.0. Rungu worked with 1UP USA to develop the rack specifically for Rungu Dualie E-Bikes. To consider other options, read our blog post to learn what works best for you.
Are there any saddle options for riding bumpy trails?
Rungu's "hard-tail" design combined with the 4.8" tires gives some cushion to your ride, but you may want more. For that reason, we offer accessories that soften the ride - Rear Suspension Options. Both are "easy-to-retrofit" accessories that you can purchase after you've experienced riding with the standard saddle.
Can I custom order a Rungu?
Yes. For paint/wrap, we offer a custom powder coat option and the option to have your Rungu Dualie wrapped (think camo). Though we offer a number of factory-upgrades and configurations, the team at Rungu can also work with you to source special components to develop a custom quote. Special rates and lead times apply. Custom orders void our Return Policy. Our 2-Year Warranty doesn't change.
Can I buy one with an internal-geared hub (IGH) instead of a derailleur?
Yes. We do offer a Rohloff Speed hub customization, which is the only IGH available that can tolerate the torque output of the motor used by Rungu Dualie. Click/Tap here to learn more.
Can I ride Rungu Dualie/Dualie XR on the street or just off-road?
You can do both but be aware of local e-bike laws.
Rungu Dualie is designed to tackle the challenges of off-road riding, so the power specifications are beyond those for many prevailing e-bike classifications. As an example, the State of California classifies e-bikes as three different types – all with a maximum power output limit of 750W. Class 1 and Class 2 E-Bikes must have a maximum speed limit of 20 mph and Class 3 is allowed up to 28 mph. In Europe, maximum power limit for legal on-road use can be as low as 350 W. The nominal output for a Dualie mid-drive motor is 1,120 W with a maximum output of 1,429 W (just under two horsepower).
Rungu Dualie has on-the-fly configurable power levels, so you can comply with many prevailing e-bike laws by electronically changing your power setting. We ship each Rungu Dualie model configured with 5 power levels – each increment represents 20% of nominal/max power. To operate completely within California Class 2 (throttle or pedal assist), you can set the power level to 2 (40%), which equates to a nominal power output of 400W with a peak at 580W. To operate within the 350W threshold, set the power level to 1, which limits the power output to 200W with a peak of 290W. You can achieve power levels even closer to the maximums allowable by law, by reconfiguring the display to show 9 power levels of 10% each (the first level is 20%).
You can custom configure your Rungu Dualie to comply strictly with local laws at the time of order. The team can then reprogram and configure your order so it strictly complies as a Class 1 or Class 2 E-Bike. Each reconfigured E-Bike gets a label identifying tits class per your order. For additional questions and considerations, contact sales@rungudualie.com.
Can I buy one outside the USA?
Yes.
We ship Rungu all over the world. Rungu offers special programming for Canadian Customers to meet Canadian homologation requirements and to simplify import procedures. Contact sales@riderungu.com to learn how we can ship one to you, or if there is a distributor in your country, redirect you to their sales department.
Is it as stable as an Adult Trike?
No, but it’s not as difficult to operate at higher speeds either.
Read this blog to learn if Rungu is stable enough for you and your riding purposes.
What kind of generator can I use to recharge a Rungu Dualie/XR in the backcountry?
You can use a gas generator or solar generator to recharge in the backcountry. This blog details how to select a gas generator and how to predict the number of batteries you can charge with a tank of gas. The blog also helps you understand solar generator requirements if you prefer to use solar for backcountry battery charging.
What does "E-Bike Class" mean? It's a drop-down on the Rungu Dualie configuration pages.
When you order a Rungu Dualie E-Bike online, you select the E-Bike class depending on your intended riding location. If there are strict laws governing E-Bike access to Class 1 E-Bikes where you want to ride, the team can convert your order to meet Class 1 requirements and label the bike accordingly. If you're planning to ride mostly off-road, Rungu strongly recommends sticking with Off-Road as this provides full power delivery. Contact sales@rungudualie.com for more information.
