Pedal first or Immediate Start

(1 replies)

Can I start from a "dead stop" or do I have to pedal first?

Posted by Guest on 07-27-2009 at 1:33pm

Immediate Start

The E-BikeKit™ hub motor system is designed with "Hall Effect" sensor wires that allow you to start using battery power from a complete standstill or "dead stop". Some motors require pedaling to engage the battery power and also require you to move above a certain speed before the controller will convey power to the hub motor. The E-BikeKit™ system is a is a "power on demand" system and can be driven completely on battery power alone if desired.

Jim - Adding an On/Off Switch to your E-BikeKit Controller

(1 replies)

I just purchased one of your e-bike kits. It does not include an on / off switch or keyed switch. What is the best way to wire one in on your systems? Tap into the hand brake wires or open the wires from the batteries?

Posted by Guest on 08-29-2009 at 1:07pm

Technology Consultant

James, The kits were designed to use a contacter (switch) at the battery source.

If you are not using a battery provided by e-bikekit.com but rather are providing your own battery then you will have the SLA harness.

The very thin red wire which loops back around into the main power wire can be clipped (at the point it mates with the large wire) and spliced into a small SPST switch of any type with a sufficient volt/amp rating to the main pack power.

This tiny wire is basically an ignition sense wire and should be used if you plan to leave your eBike sitting for any length of time > 10 minutes without disconnecting the main battery.

The advantage to using this "remote ignition wire" is that when it's in the off position the controller uses almost 0 power. When it is on, the controller (even if your not riding) will draw a small amount of current (.53 ma) as long as the battery is connected.

By using the remote ignition wire and installing a switch inline, you can ensure that your battery is ready to go and doesn't loose any power you haven't used riding.

Hope this answers your question in enough detail.

Regards, Mike Keefer mkeefer@e-bikekit.com

What is the cutoff voltage for the controller, is it configurable?

Posted by Andy on 09-30-2009 at 6:14pm

The controller Low Voltage Cutoff is 29~30v

The controller Low Voltage Cutoff is 29~30v, it can be changed via resistors on the circuit board but usually adequate for most 36v packs. It will work with a 48v pack as well hot off the charger at 56v ( this will increase motor speeds significantly however !!)

I commute 40 miles each way with a 1600 ft climb / descent in the middle. On alternate days I drive to work and ride home, and ride to work and drive home. My bike weighs 18 lb. I want to add electric assistance to it, but I cannot find a kit that is light enough. Since I am able to do it without electric assistance at all, and since the energy to weight ratio of Li-ion batteries does not change with size, I want to build a 28 lb electric-assisted bike, and I expect it to be not slower than my 18 lb bike over this 40 mile course. However small, the kit should always carry its own weight and then some. Can you help?

Posted by Osman on 01-21-2010 at 1:59pm

Chief Mechanic

Commuting on an e-bike through hilly or mountainous areas can be a challenge. Our 6x10 motors are designed for just such a task. 40 miles, on the other hand, is a long distance for one battery. Our LiFePO4 10AH battery can deliver ~20 miles per charge. A battery that could power a 40 mile ride would weigh at least 18lbs on its own.

Disc brakes on front wheels - available with bolt-on disc brakes late August 2010

Newly Designed Rear Direct Drive Motor Now with Standard 6 Bolt Disc Brake! (started march 2010, FRONT geared and direct drive motors available with bolt-on disc brakes late August 2010) The latest rear motor design from E-BikeKit is 100% ISO standard disk brake compatible. The new design completely eliminates the need for an "offset lacing pattern" to center the wheel. Now with a standard lacing pattern the rear wheels are perfectly centered. This new design combined with the fact that all E-BikeKit wheels are professional built in the USA by hand makes a strong case for the E-BikeKit rear wheel being the best available rear hub motor wheel available.

Crystalyte controllers with EBK motors - will work

Yes, it works. The colors may not be exact matches between Crystalyte controller and EBK motor, but we have a thread on ES with all sorts of known combinations: http://www.endless-sphere.com/forums/viewtopic.php?f=2&t=6241&start=0 The thing to do is flip the bike upside down and mark down what combinations you have tried, one combination will run forward, and another in reverse, the others will not start from a dead stop or will run rough , don't hammer the throttle, just gently apply power and it will be obvious when you get the right combination.. if it's running rough, don't keep throttling on. " Methods " on ES would know this by heart for sure. Ebike-modding.. always fun !

Posted by William Wagner on 11-21-2010 at 9:42pm

Rain and Rolling Resistance...

Both the direct-drive and the geared hub motors from E-BikeKit are water resistant. The direct-drive motors have an oil seal and can actually be run under water for days without a problem. The E-BikeKit LiFePO4 battery packs are also treated to be 99% water-resistant and rain presents no problem. The direct-drive motors do have a minor drag to them.

Geared Vs. Direct Drive Motors

The two types of hub motors offered by E-BikeKit are geared and direct-drive motors. Each motor has unique properties that may be more suitable for you. Choosing the best option for you will depend on your riding style.

Geared Vs. Direct Drive Motors

GEARED MOTORS

Electric Bike Motor - FRONT - Geared

DIRECT-DRIVE MOTORS

Electric Bike Motor - FRONT - Direct-Drive

Power/Torque
36v (350-450w)
36v (500-750w) / 48v (up to 1000w)
Speed
36v (17.5 MPH)
*Unassisted on flats
36v (20 MPH) / 48v (28 MPH)
*Unassisted on flats
Range
16-40 Miles/9.5ah LiFePO4
*Rider weight, rider input and terrain contingent
12-34 Miles/9.5ah LiFePO4
*Rider weight, rider input and terrain contingent
Diameter
(top to bottom)
134mm Diameter
244mm Diameter
Weight
7 pounds
14 pounds
Freewheel
Zero drag when battery is not engaged.
Minor drag when battery is not engaged.

350w Internally Geared Motor

Advantages vs. Direct-Drive:

Lighter Weight (7 pounds vs. 14 pounds)
Smaller (134mm diameter vs. 244mm diameter)
Zero Drag (no resistance when not using battery vs. slight resistance)
Excellent Efficiency (15-25% more range)

Disadvantages vs. Direct-Drive:

Lower Top Speed (17.5MPH @36v vs. 20MPH)
Less Power (350w vs. 500w = 15-25% less hill-climbing strength)
Moderate Life span (internally geared parts will wear down 2+yrs expected)
Limited Warranted Use (warranted 2yrs / 36v use only)

500w Direct-Drive Motor

Advantages vs. Geared:

High Top Speed (20MPH vs. 17.5MPH)
More Power (500w vs. 350w = 15-25% more hill-climbing power)
Excellent Life span (brushless and no friction = "last forever" 5+yrs expected)
Warranted for 48v Use (warranted 2yrs / 36v or 48v use)

Disadvantages vs. Geared:

Heavier Weight (14 pounds vs. 7 pounds)
Larger (244mm diameter vs. 134mm diameter)
Slight Drag (slight resistance when not using battery vs. zero resistance)
Moderate Efficiency (15-25% less range)

Practical Summary:

If you plan on pedaling more than using the battery, are willing to sacrifice power and top speed in favor of lighter weight and you want your bike to remain more of a conventional bicycle then the 350w geared motor is likely a better choice.

If you plan on using the battery more, desire a higher top speed/the ability to run at 48v(28MPH) and more power and are less concerned with the heavier weight then the 500w direct-drive motor is for you.

Both motors are the exact same price and both are EASY to install.

Does the controller limit the hub motor to any specific rpm? What is the maximum no-load rpm of this motor?

(1 replies)

Posted by Guest on 12-03-2010 at 11:23am

Controller and motorss with regard to RPMs

There are 2 rpm models, one for 20" bicycle wheel and the other for 26", both provide a loaded speed of slightly more than 20mph on 36v. Obviously, the 20" model will spin faster to compensate for the wheel diameter difference. The motors are not rpm limited by the controller, it's all a factor of voltage, more volts = higher rpm. The stock controller can be operated on a 48v battery pack safely and the throttle ( 0 to 5v Hall type ) allows immediate start from a dead stop via hall sensors in the motor. 24", 26" and 28" direct-drive motor will spin 9 rpm/volt.

What are the advantages of a front hub over a rear hub, or the other way around

Posted by Henry on 12-19-2010 at 2:29pm

Front vs. Rear

The requirements, advantages and disadvantages of front versus rear wheel hub motor conversion system

Front Wheel E-Bike Conversion:

Requirements:

-100mm between front dropouts
-MUST use a Universal Torque Arm & C-Washer (when appropriate with certain alloy or quick release forks)
**Using the "C-Washers", the "Inside Safety Washers" as well as a Universal Torque Arm ensures a safe to install of the front wheels on "non-steel" & quick release forks.

Upside:

-Easy install (no derailer adjustments)
-Improved weight distribution (assuming battery is above rear wheel)

Downside:

-Decreased traction off road or in wet condition on steep inclines.

Rear Wheel E-Bike Conversion:

Requirements:

-135mm between rear dropouts
-Universal Torque Arm is Highly suggested

Upside:

-ISO Disc Brake Compatible
-Better traction off road & in wet conditions

Downside:

-Increases weight in back (assuming battery above rear wheel creates more stress on rear wheel)
-Limited to 6 speed freewheel. Available freewheels are 1 speed, 5 speed & 6 speed
-Minor adjustment may be required for derailer if coming down from anything above a 6 speed freewheel

E-Brakes

(1 replies)

I noticed for the product updates that E-Brakes are not used anymore. Does this mean that the rider needs to remember to cut power at the throttle when braking? Or does the power stop based on some other sensor? Or perhaps, did you find out it was OK for power to continue to the motor when braking? Thanks in advance!

Posted by E-BikeKit Novice on 04-12-2011 at 12:39pm

E-Brakes

The E-BikeKit Hub Motor is only engaged when you apply the throttle. The E-Brakes were designed as an added safety feature for emergency situations. God forbid anything were to happen like the throttle were to get stuck or you couldn't let go of the throttle - by applying the E-Brakes you cut power to the Hub Motor.

Alloy Forks & Front Motors

(2 replies)

I see you have C-Washers to allow use of front motors on alloy forks. I'm interested in this because I'd prefer a front motor for various reasons, and I don't want to change my front alloy suspension fork. However, I've read elsewhere that the torque from the motors can crack alloy forks, and that this is fairly common. The C-Washers seem to address axle spin issues, but I don't see how they would help to prevent this cracking issue. Are the other sites over-blowing this potential problem? Thanks!

Posted by E-BikeKit Novice on 04-12-2011 at 12:44pm

Alloy Forks & Front Motors

C-Washers are designed for Front Wheels that have quick release. They fill the recessed area in the drop-out so that the rest of the hardware can mount flush. The E-BikeKit Universal Torque Arm is designed to spread the torsional strain from both the Direct Drive Hub and the Geared Hub Motors. I'm not sure as to where you may have gotten your information from but it doesn't sound correct. The Universal Torque Arm is designed to prevent cracking or breaking of the drop-outs.

What is the added weight of the entire system (for each application)? I know I will not be able to hang my bike upside down from the ceiling hooks any longer. Also, I've read the 48v battery is 27lbs. Is that the weight of the battery by itself?

Posted by Guest on 07-12-2011 at 7:25am

Added Weight

The added weight depends on the system you select.

The Geared Hub Motor weighs 7 pounds and the Direct Drive Hub Motor weighs 14 pounds.

The 36 volt 9 amp hour Sealed Lead Acid Battery weighs 16 pounds, the 36 volt 15 amp hour Sealed Lead Acid Battery weighs 27 pounds, and the 48 volt 9 amp hour Sealed Lead Acid Battery weighs 21 pounds.

The controller weighs around 1 pound and the combined weight of the wiring weighs around a pound. You will also need a rack to put your battery on which could add another 5 pounds for a steel rack or less with a seat post rack.

Dual motor bicycle?

(5 replies)

Hi guys, I have one of your hub motors on my front wheel and love it. I was wondering (while it would not be street legal,) is the design of the motors such that adding a second motor to the back wheel would increase speed, and if so, by how much?

Posted by E-BikeKit Novice on 02-06-2012 at 2:01pm

Dual Motor Bike

Dual Motor E-BikeKit System The way it works is 2 motors, 2 controllers, 1 battery 1 throttle. The throttle is powered by one controller only, but feeds speed signal to both. You join the signal wires from both controllers to one throttle but the power wire from the throttle only to one controller. This is how to wire a dual wheel system using the E-BikeKit. E-BikeKit does not support this modification. Users that attempt to re-wire thier systems for dual-motor use are on thier own. Proceed with caution as any modifications like this will immediately void your original E-BikeKit warranty. As of 1/15/2012 E-BikeKit is in the process of developing a dual-motor system that will work out of the box without any need for modification. When that happens there will be an update to this post.

Controller

(1 replies)

If I start with a SLA battery and then down the road decide to upgrade to a LiFePO4 battery can I use the same controller?

Posted by E-BikeKit Novice on 05-25-2012 at 9:21am

I was just wondering why you offer a 72V controller upgrade. Can your Hub motors be used with 72V battery packs??? I couldn't find any information about the upgraded controller or it's use with your ebike kits.

Posted by E-BikeKit Novice on 06-17-2012 at 9:00am

72v Controller

The E-BikeKit Direct Drive Rear Kit is the only kit that can be upgraded to 72v. We offer an upgraded controller which warrants usage at up to 72v.

Rear Hub Motor Axle Length

(1 replies)

I have 165mm inside dropout spacing with disk and 6speed on my rear fork, My present rear axle is 220mm end to end with axle bolts tightened down.I want to buy your kit because of the great wiring. Is your rear axle long enough to bolt to my rear dropouts?

Posted by E-BikeKit Novice on 09-19-2012 at 8:34am

Dealing with rear dropouts greater than the standard 135mm width

The E-BikeKit rear axle measures 225mm which should be sufficient for your rear axle dropouts. That said, you may need to use spacer washers or c-washers to fill the extra space on the inside of the dropouts. Call us toll free at 1-866-882-3245 to order any small parts like these specialty washers.

New power connectors

I want to buy and build my own sla pack. Does the kit come with a new style lockable plug for me to solder on to my battery pack or can I just cut it off the controller and use Anderson's? I would prefer Anderson's only instead of needing to solder connection types to my pack. (One for charging and one to the controller)

Posted by O2 on 11-10-2012 at 10:09am

Electric Bicycle Build-Your-Own SLA Kit

The Electric Bicycle Build-Your-Own SLA Kit actually comes with two battery wire harnesses for charging and discharging your SLA battery. For those that intend to use the Electric Bicycle Build-Your-Own SLA Kit with the E-BikeKit conversion kit one of the wire harnesses is the latest style locking 2-prong and one is Andersons.

That said, we're happy to provide both with Andersons by request. Simply contact us by phone at 1.866.882.3245 to place your order.

Posted by E-BikeKit Novice on 11-16-2012 at 4:25pm

E-Brake

The E-BikeKit electric brakes are designed to cut power to the motor when you grab them. Its an extra safety feature and required by law in some states. E-brake handles may be left unattached or you can use either left or right or both. For the E-TrikeKit you may specify your e-brake handle configuration when ordering.

Freewheel spacing

(1 replies)

For rear wheels, what is the limiting factor on freewheel size? The Kit Info: Front vs Rear page states "Limited to 7 speed freewheel. Available freewheels are 1 speed, 5 speed, 6 speed or 7 speed." From searching through other knowledge base questions I believe it used to top out at 6 speeds. There are a couple of companies currently making 8 speed freewheels and one making a 10 speed, which would make e-conversions of modern trikes such as the Catrike Expedition a breeze if they will twist right on. If it is a spacing issue can an experienced mechanic space the axle and redish the wheel to accommodate a freewheel with more speeds? Thanks!

Posted by Nick F on 12-20-2012 at 1:49pm

Freewheel Spacing

The current limit on spacing allows for a 7-speed freewheel on all E-BikeKit hub motor wheels. This is expected to change with the introduction of a new model kit in 2013. The new model will allow for 10 sprockets and will be cassette compatible as opposed to freewheel.

Pedaling in conjunction with the battery and motor

Pedaling is encouraged. The more you pedal the farther your battery will last per charge. You can pedal and use the motor in combination and in any ratio.

Why do you not offer 36/48 volt 20 amp fuses and links to provide short circuit and overdraw protection? Weight not an issue, I am using 3 12v 109 ah deepcycle marine batteries with your 500w trike kit as a pedaling assist. My only fear is a wiring short or overdraw. Your warranty is only void for over voltage. So are you implying the system will Not ever draw more than 20 amps @ 36 volts even under extreme load?

Posted by John blackhurst on 02-27-2013 at 2:38am

PWM - Pulse Width Modulation / Current Limiting

The controller is Current Limiting ( via pwm " Pulse Width Modulation " ) , and it will not allow more than 20 amps, regardless of load, even under stall conditions. Adding a fuse to protect against short circuit would be a good idea, but not absolutely required to protect the controller/motor..

Power Switch

(1 replies)

I have a 48v 20ah liFePO4 battery and I would like to be able to leave it plugged into the controller without it discharging when not in use. I don't like to disconnect the battery often because when I reconnect it, the spark caused by the inrush of voltage to the controller degrades my connectors. I noticed there is a small red wire coming out of the controller that is paired with the larger red wire at the power pole connector. Is that where I could insert an on/off switch? Would that prevent the Capacitor from draining battery power when off?

Posted by Brian on 04-30-2013 at 7:01am

Re: Power Switch

We can't recommend that you add a switch to that wire. Modifying your kit will void your warranty, and it might be unsafe besides. We recommend that you use the kit's on/off switch to turn it on and off. On the 2012 (and earlier) kit, this switch is on the controller. On 2013 kits with LCD displays, hold the red power button until it turns off.

Re: Alloy suspension fork

It's okay to use our motors with aluminum forks, but you need to be sure to use the right hardware, including C-washers and a torque arm, to prevent damage to your bike and possible injury. For riders over 200 pounds, we recommend using a rear motor.

Posted by E-Bike Novice on 07-07-2013 at 11:55am

Re: Solar Charging E-Bike?

We currently don't know of any good solution for solar charging your E-Bike. If you're trying to save money on your power bill, though, don't worry! It costs less than a quarter ($0.25) to charge your E-bike up, so it might make sense to let the utility company handle it and subscribe to a "Green Energy" utility instead. See this article. On the other hand, there's a lot of homemade solutions - a google search will show a whole variety, but they tend to be big, awkward, and take a long time to charge the bike up.

Re: Voltage?

The voltage of the kit will affect its speed.

The E-BikeKit is 36 and 48v compatible. There is information on the kit available on our Kit Info page, which tells you about distances, top speeds, and the difference between geared and direct-drive. You can look up your average top speed in this table:
