Motor Simulator

Our ebike motor simulator lets you simulate and compare different ebike setups, including speed, power, efficiency, and heat, before you build. A wide selection of hub motors are modeled, and you can add custom batteries and controllers and set vehicle parameters like throttle level, bike weight, and hill grade to see how they affect performance. You can even compare two setups at a glance, and at higher power levels and hill grades, get an estimate of how long it would take the motor to overheat.

Trip Simulator

Grin's ebike Trip Simulator — model range, speed and battery use on a real route before you build, so you pick the right motor, battery and gearing.

Trip Analyzer

The Trip Analyzer lets you view trip log data from the Cycle Analyst and Analogger in order to see your energy usage and other stats from an ebike trip. With the GPS Analogger, you can see your exact route location on the map and all your electrical details at any given point on the way. It is also possible to upload and share trip logs in order to compare and scrutinize the energy usage and performance of your setup.

Spoke Calculator

Our spoke length calculator computes the exact spoke length for hub motor and ebike wheel builds, and is the only one we know of that includes the paired spoke holes in the flange common on large diameter hub motors. It also draws an automatic side view of the laced wheel and computes the spoke nipple angle at the rim. Choose from a drop-down list of common hub motors and rims, or measure your own hub and rim and plug in the numbers if it isn't listed.

Charge Simulator

The Satiator Charge Simulator is a web application for creating custom charge profiles for your lithium battery pack. It allows you to view a simulated charging graph to see the charging time in difference scenarios, produce partial charge profiles to maximize battery cycle life, and download the resulting profiles to your Satiator charger to use on your actual battery.
