Which Super73 bike is right for you? 


HEIGHT/WEIGHT RECOMMENDATIONS:
 All models have a weight capacity of 125 kg/275lbs. Our SUPER73-ZG model is recommended for riders 6ft. and under and 
was made with specifications geared toward Generation-Z, meaning they are a younger audience and typically have a smaller frame. While there are plenty of riders who exceed 6ft. who have chosen to ride the SUPER73-Z Series bike, we typically suggest the SUPER73-S Series for someone needing more leg room. The S-Series models accommodate a wide variety of heights and will work for someone above or below 6ft. We offer extended seats as an additional accessory for the SUPER73-S Series for optimal leg room and comfort. See below for seat height from the ground:

  • ZG - 27"
  • SG1 - 32"

HILL CLIMBING AND COMMUTES: If you are going to be climbing a lot of hills and using your Super73 for commuting over 20-30 miles daily, we recommend the SG1. If you plan on cruising over short distances, in cities, small towns, or on flat surfaces and don't need that much power, we recommend the ZG or SG model.  

E-BIKE LAWS AND REGULATIONS: The Super73 S-Series and Super73-ZG models are both certified Electric Pedal Assist Cycles (EPAC) under EN 15194. They do not require a license or registration. 

 

What's the difference between hydraulic and mechanical disc brakes? 

The major difference between hydraulic and mechanical disc brakes is that the latter uses a cable similar to a derailleur cable, while the former uses brake fluid similar to what’s used in cars.

As previously mentioned, mechanical brakes make use of a cable in order to brake. Just like a derailleur cable, dirt can affect their performance and stretch them out. Mechanical brakes do not stop as efficiently as hydraulic brakes, however the simple cable makes them easier to adjust. Mechanical brakes offer easy adjustments if you like adjusting your brakes on the fly, and are more common as well as cheaper to replace.

Hydraulic brakes are designed to use brake fluid, which becomes compressed when the brake lever is squeezed and allows the brakes to function. This is a superb technique that offers stronger, more reliable braking performance. However, the technique will cost you more than the brakes themselves. You will have to ensure that the brake lines are air free, and maintain care for the brake fluid in case their performance starts to suffer.

Just like with brakes of your car, you will have to change the fluid at times. (Luckily this only needs to be done every so often.) Keep in mind that these brakes are in an enclosed system, meaning you don’t need to worry about mud and dirt affecting the performance of your bike. The only exception for both hydraulic and mechanical brakes is if the pads themselves get dirty.

Hydraulic Brakes Pros and Cons:

PROS

  • Excellent modulation
  • Unsurpassed stopping power
  • Open Systems with huge rotors capable of handling very high loads of heat from “heavy-duty” riders

CONS

  • More expensive
  • Closed systems can blow off or lock-up or blow-off hydraulic seals/lines if overheated

What's so cool about the Tektro brand? 
Tektro is a popular and well established bike component manufacturer. You can benefit from Tektro's own manufacturer warranty if you need replacements parts. Just contact them directly by finding a local dealer through their website. 

What is the difference between a 2A and a 5A charger? 
In simple terms, a 5A charger will charge your battery faster than a 2A charger. The 5 amp (A) charger allows more current to pass to charge the battery. You can use the 2A charger on any battery but the S1 models all come with a 5A charger. 

What is Pedal Assist? 
Pedal Assist automatically turns on the motor when you pedal. With pedal assist you do not need to use a throttle to control the motor. 

There are two types of Pedal Assist: Cadence Sensor Type which measures IF you are pedalling and a Torque Sensor Type which measures HOW HARD you are pedalling. The Super73 S-Series sold in the United States with thumb throttles, as well as the Super73-SG (Global) has a cadence sensor. The Super73-SG1, sold outside North America without a throttle, has a torque sensor. 

1. Cadence Sensors
The basic cadence sensor uses a magnet on the crank, turning the motor ON when you start pedalling and OFF when you stop. It works more or less like a switch. You control the boost level and speed by adjusting the assist mode manually up and down. 

The advantage is that it's an inexpensive way to get some sort of pedal assist onto the bike, but the disadvantage is that the pedal assistance can feel jerky, laggy and counterintuitive. If you want to pedal faster than the motor is spinning, the motor will actively work against your efforts. The Super 73 has a cadence sensor as it is most often used with the throttle only.


2. Torque Sensors
The torque sensor uses a precision strain gauge, measuring your actual force on the pedal and sampling at 1,000 times per second over the entire pedal stroke. 

The harder you pedal, the more power it gives to the motor. If you pedal lighter, less power goes to the motor. The adjustment is made in real time amplifying your every input. 

Most higher-end e-bikes use torque sensors, however in some countries cadence-only sensors are not allowed. The disadvantage is the cost is significantly higher to implement this technology as the precision component is relatively more expensive.
