Frequently Asked

The "Off-Road Package" and Unlimited Mode: See information here

VIDEO: RX and S2 Riding Modes Explained

Information on the iOs and other features is not yet published. Detailed product and pricing information on the Off-Road Packages will be announced before bikes are delivered. 

Pricing of the off-road throttle will be similar to the throttle for the SG1 (150€ TTC). It is possible to purchase it on the S2 or RX after preordering an RX or S2, and even after purchasing and adding it post-receiving the bike. It is a simple plug and play solution.
It is not compatible for SUPER73-ZG or SG1 models. Side note: the ZG model is not compatible with off-roading throttles. 

Certificate of Conformity EN 15194
Please e-mail us to receive the certificates of conformity for the ZG, SG and SG1 models. S2 and RX models will have certificates available upon time of delivery. 

Can I ride my Super73 in the rain? 
Yes, you may ride your bike in the rain. Note that the Super73 is not meant for use in puddles, heavy rain, and riding through streams. Never immerse this product in water as the electrical system may be damaged. Take extra care while riding in wet conditions. Feet or hands can slip in wet conditions and lead to serious injury from a fall. Learn to brake earlier and gradually as it will take longer to slow than when operating in dry conditions. It is recommended to decrease your riding speed as well as it is important to wear reflective clothing and use approved safety lights. Road hazards are more difficult to see when wet, proceed with caution.
If you leave your bike out in the rain, make sure the battery connectors are covered and dry before placing your battery on it. 

Repair/Servicing: What happens if I have an issue on my bike, who do I call? 
Super73 bikes are simple to service, and beyond the electronics, have standard bicycle components. This means that for any typical flat tire replacement, brake adjustments or yearly maintenance you can go see any bike shop. 
For electronics repair and troubleshooting (battery, motor, display, lights, etc) please contact us directly via e-mail or phone. We are located in Amsterdam, The Netherlands and can help you trouble shoot easily. In this case, we work together to figure out the problem and find a solution. Sometimes this can be easily solved over a message, phone, or a video call with our technician. If there are parts to be shipped, we can do so from our warehouse Amsterdam and takes a few days to reach you. We use a Warranty Return Form to fill in if parts are needed to be returned. To help expedite the process, when contacting us please make sure you have your original invoice, bike frame serial number, photos and / or videos of the issue and clear description of the problem you are experiencing. 

Tip: Spare tubes may be handy to purchase in advance as those are more uncommon to find in bike shops. 

Please make sure you also understand our warranty agreement

Why are Super73 sold in Europe priced differently than Super73 sold in the USA?
Europe has a different set of rules, certifications, market standards and regulations which we have to uphold. This combined with different duties and pricing structures when bringing our bikes to Europe, are the main source of the price differences. See below for further explanation. 

  • RX and S2: The best specs for the European market
    While the Super73 RX and S2 models sold to the US market have optional gearing, we automatically included those features on the bikes we import to Europe. We also upgraded the brakes to Magura a trusted high-quality brand from Germany. The bikes have the same build, design, and features, but on the European market, we chose to offer only the best.

  • Certified and eligible for government incentives
    In terms of regulations and certification, Europe indeed has some of the highest standards regarding electric bikes. Super73 follows those regulations to ensure consumer safety. We therefore test each new bike model in accredited laboratories (such as TUV SUD) to make sure we follow all the required labelling and standards. The United States does not require those same tests or standards.These tests and certification do have an influence on our prices. Thanks to this, our bikes are certified Electric Pedal Assist Cycles (EPAC) and fall in the e-bike category required to receive government grants for end consumers.

  • Prices are not always what they seem
    At first glance, you may think that prices labeled on the US Super73 website are much lower than prices displayed on the European site. In the United States, advertised prices don’t include local state taxes, which range from 0% to 13.3% (such as in California). Those state taxes are added to the shopping cart. In Europe, the VAT is already included in the price displayed on the product page. On top of that, there are different import fees and other Value Added Taxes added to products coming into Europe.

What is the range difference between the SUPER73-SG, SG1 and ZG models?

  • SUPER73-ZG has the smallest battery, 313 watt-hours, and a range of more than 45 km* on ECO pedal assistance mode.
  • SUPER73-SG, has a 422 watt-hour battery, provides an estimated range of more than 50 km* using the ECO pedal assistance mode. If you are in SPORT mode at 25km / h the range is about 25-30km.
  • SUPER73-SG1, has a 969 watt-hour battery, has an estimated range of more than 80 km* using the ECO pedal assistance mode. If you are in SPORT mode at 25km / h the range is about 50km.
    * Estimates of battery life depend on conditions such as rider weight, speed, temperature, wind, tire pressure, terrain, incline, etc., and therefore range may vary.

To give a concrete example in Paris, a ride in SUPER73-SG1 with a distance of 11.4 km on uneven, paved and sloping terrain from the 18th arrondissement to the Parc des Princes in Boulogne, lasts about 45 minutes and is easily done on a SUPER73-SG1 in SPORT mode at 25 km / h used most of the time, with a rider weight of 75 kg. The battery does not need to be recharged for the return. If you are using a SUPER73-SG battery (422 watt hours) for this same route, a charge in between would be recommended.

Do you offer financing? 
We are actively working on setting up financing for our customers, but some banks offer individual financing. Please check with your own bank as some offer small loans for electric bikes. To go to our grants and financing page, please check here.

Can I add a suspension fork on my SUPER73-SG or SG1 that has the fixed handlebar?
It is possible, however we do not supply the handlebars. You would need to use a handlebar with a 22.2mm tube size (this the size we use) Other than that, it is your choice which brand, material etc you choose. We always recommend safety first!
