Here at Kobois, we feel the CA is an invaluable asset to go along with your controller. There are countless features incorporated that allow you to set all kinds of parameters on the controller itself, But to simplify we feel the most important is the fact that you can set the AMPS leading from the controller to the motor itself,this is HUGELY IMPORTANT because if your controller is say 40 Amps,,being that you are on this site our lowest rated controller is in fact 40 Amps that makes for a very powerful controller to be sure as most regular controllers on the market that are installed on most type of “store bought” e-bikes are rated from as low as 10 to 15 Amps,those controllers in general are cause for very weak and uninspired rides that tend to MAX OUT at 28 to 32 kmph speed, and those types of set-ups will slow to a crawl on any hills you may encounter as well as higher than normal winds. (the type of motor used on the set-ups also will be a determining factor in terms of speed and overall Climbing power as well as wind resistance) That being said using a controller that is rated at 40 Amps will in fact deliver the full power of the controllers capabilities. But there is a cost at riding at 40 Amps and that cost is RANGE. So if for example you have a battery set-up of 48V15AH Using a powerful controller of 40 Amps will allow a range of approximately 25kms in real world terms,but having the CA allows you to adjust the AMP DRAW,,,so lets say you want a long range ride,simply set the amperage on the CA to say 20 amps,this will greatly extend the range of your ride to at least 50kms.(Believe or not setting your controller at only 20 amps still provides for a nice exhilarating ride still attaining speeds of up to 50kmph and has good hill climbing ability as well when using the 3540 Crystalyte motor @ 48volts ). For this reason alone,having the ability to program the amps at any level you wish from 1,2,3,4 amps UP to the capacity of your controller (if your controller is rated at 40 AMPS you can set the CA to that maximum,,,if your controller is rated at 60 amps then that is the MAXIMUM setting from your CA allowable for that controller) warrants the investment of this phenomenal product.

Another invaluable Feature is the Speedometer, Distance, Time: All of the basic features of a bicycle computer, including the average and maximum trip speeds, plus a total distance odometer.

Once connected to your controller, the Cycle Analyst calculates and shows the following information as well:

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.

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.

Furthermore, the Cycle Analyst has the ability to over-ride the user’s throttle and regulate the power delivered to the motor, turning an otherwise dumb ebike into an intelligent device with a user programmable speed limit, current limit (as discussed earlier), and low voltage cutout.

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.

Additional Features

Remote Shunt: Unlike the watt-meters and amp-hour meters designed for RC hobbyists, the Cycle Analyst uses a remote shunt for sensing current rather than running wire through the meter, so you do not need to route heavy gauge battery cables up to the handlebar and back.
Backlit LCD: The display readout is well illuminated for night riding.
Water Resistant: The circuitry is fully enclosed in a sealed box enabling it to withstand exposure to wet and rainy conditions.
Handlebar Mounting: Easily attaches to handlebar tubes from 7/8″ to 1 ΒΌ” diameter with included hardware.
Save on Power Down: Trip data such as amp-hours and distance are saved when the meter is shut off, and are restored when power is re-applied.
Fwd and Negative Amps: Both positive and negative amp-hours are displayed separately, so you can calculate accurate regenerative braking statistics or use it to monitor charging currents as well.
Wide Voltage Range: Operates from 10V to 150V, accommodating the vast majority of all small electric vehicles. A high voltage option for use up to 350V is available on special request.
Flexible Speed Input: Detects vehicle speed either with a magnet and sensor cable or through the hall effect signal on brushless motor controllers.
Data Logging: Devices have a serial output stream that can be used for real-time recording the vehicle statistics to a computer or laptop. You can Purchase here:
