The Cycle Analyst V2.4 is the first digital dashboard and battery monitor originally designed around the specific needs of electric bicycles. However, the flexible setup configurations, wide feature range, and affordable price have led it to widespread appeal in a range of other EV applications. From the dashboards of MIT’s solar car, to record breaking electric motorbikes, to small trains, powered wheelchairs, and even sailboats and airplanes, the Cycle Analyst has become the e-meter of choice for keeping track of the vehicle’s battery usage and performance characteristics.
- Volts, Watts, Amps: The instantaneous electric power being drawn from the battery.
- Amp-Hours, Watt Hours: The net energy that has been pulled from the pack since the meter was reset. The accumulated amp-hours let you know the remaining energy in the battery pack with far greater accuracy than a voltage or LED indicator.
- Speed, Distance, Time: All of the basic features of a bicycle computer, including the average and maximum trip speeds, plus a total distance odometer.
- Regen, Wh/km: There are several quantities this meter will calculate that you don’t get with other instrumentation, such as the % extra range that was gained from regenerative braking, as well as the vehicle’s average energy use in Watt-hours per kilometer or mile.
- Peak Currents and Voltage Sag: Records the maximum forwards and regenerative currents as well as the minimum voltage on the battery pack.
- Total Battery Cycles and Amp-Hours: Retains life cycle information on the vehicle’s battery pack, such as how many charge and discharge cycles the pack has experienced and the total amp-hours that were delivered over its entire life.
- Speed Limit: This has the utility of providing legal compliance to the speed cap imposed on ebikes in most jurisdictions. When used with a full throttle, it serves as a cruise control on the electric bicycle. It can also be beneficial to riders who want to increase their torque and power by using a higher voltage battery, without simultaneously increasing their top-end speed.
- Current Limit: An adjustable amps limit is useful to prevent damage to the batteries from excessive current draw, to increase the range that you’ll get on a charge, and to protect the motor controller and motor in setups that draws too many amps.
- Voltage Cutout: A low voltage cutout is used to protect a battery pack from being discharged too deeply, which can cause cell reversals in NiMH/NiCad packs, permanent cell damage in Lithium packs, and sulfation in Lead Acid batteries. The programmable low voltage rollback allows you to set an appropriate low voltage point tailored to your pack.
This version is for the “Direct Plug” model, which uses the motor’s hall sensor signal to determine the RPM/speed of the wheel. If you are building a mid-drive system or any system other than a geared or Direct Drive hub motor mounted in the front or rear wheel, we recommend the “DPS” version instead.
