STEP 6
Step 1:
Make sure there are no shock mounts or obstructions on the down tube at 6-7 inches (150mm - 172mm) from the center of the bottom bracket. This allows the Interface top cap to fit. If there is no obstruction go to Step 2..
Step 2:
At 6-7 inches measure the width and height of the down tube. This is important to determiine the fitment of the interface frame pads and the size of the top cap.
Record these. Width_________ Height _________
The interface is 80mm wide, so it will fit any bike down tube that between 35 mm - 76mm wide. In order to determine what size interface pads will be needed.
Subtract 80 mm - width = _____ /2 =_______ mm frame pads.
For instance 80mm - 65mm (width) = 15mm / 2 = 7.5 mm frame pads. So choose 8mm pads for a tight fit as the pads have a little compression built into them.
Height if 45 - 55mm = regular top cap if between 55mm-65mm = tall top cap
Regular Top Cap or Tall Top Cap
Step 3:
Do you have a Straight Down tube or a Bent down tube?
The Santa Cruz V10 is an example of a Straight Interface fitment. The Norco Sight is an example of a Bent Interface fitment.
Step 4:
What type of bottom bracket?
73mm / 83 mm / 92mm / 107mm / 121mm (can't fit)
Kranked has made it's own 30mm BB system that will work with the 73 /83/ 92 and 107 Bottom brackets. The Interface comes in 8 versions so that each BB width is fitted for BB width and frame layout ( straight and bent).
Step 5:
Drivetrain - Is there a maximum size chain ring that will fit your bike? Some bikes are being made to only fit up to a 32 or 34 tooth chainring with the rear swing arms and pivots getting tighter and tighter. The Kranked Hyperdrive comes with either a 32, 34, 36 or 38 tooth chainring.
Also are you running a Shimano 12 speed rear cog set. This needs a special chainring as the chain is narrower.

INstall Guide - prepare hyperdrive for install
Get familiar with the Hyperdrive as you unpack it. The install is the reverse of the unpack below.
-
Unpack 1
-
Unpack 2
-
Unpack 3
-
Unpack 4
The Hyperdrive comes assembled to the best of our abilities so that the unpacking of the system should be the reverse of the install. So pay attention to the details here as it's all pretty straight forward to repeat and get it right. The Hyperdrive will look like this when you receive it.
Push the chain tensioner down till it hits its built in stop. Then feed the chain off of the 46 chainring from the bottom. The chain will hang off motor freewheel which is not shown in the picture.
Next take a 8mm hex wrench and remove the drive side crank arm from the spindle. It backs off counter clockwise.
The freewheel chainrings will now slip off of the spindle. Make sure to not drop the freewheeling chainrings.
It is important to pay attention to the spindle spacing at this stage. The 46t chainring, tensioner and motor freewheel all need to be aligned so keep the spacing organized to re install as you are taking it apart.
Keep the spacer (s) from the drive side off as well as the BB dust cap. Pay attention to the orientation of the dust cap.
Take the non drive side crank arm and spindle (attached together) off. The spacers and dust cap will all stay on the spindle.
Next undo the two 4 mm hex bolts that secure the bottom bracket into the Interface. Back these out so that they are flush as shown in the picture.
Now you want to undo the 4 mm bolts that hold the top cap. Take these right off and take the top cap off. It will pull up and out.
Now the Hyperdrive Kit is ready to be installed by essentially repeating these steps in reverse.

Install Kranked QR BB system.
Kranked threaded BB's have a drive side marking machined on the face of the BB. , it is an extra line between the notches. Drive side threads in counterclockwise ( towards the back wheel.) Non drive side threads in towards the back wheel when on the non drive side. Tighten to 40 n/m both sides.
Press fit Kranked BB's also screw together and tighten with the same BB tool. They screw together using the insert sleeve. It is important to apply the proper BB grease.
Spray the down tube with a little soapy water so that the Interface pads will slide while slightly compressing over the down tube.
Take the power cable and throttle cable and loop it over the non drive side of the interface. When you slide the kit onto the bike it is important that these cables fit with no obstructions between the frame and the interface.
Now slide the kit along the down tube so that it slides into the quick release groove in the Kranked bottom bracket, both sides equally.
It is important that the kit slides in tight to both sides of the bottom bracket, so that there is no gap.
It is really helpful to have a strap or an extra set of hands to hold the kit flush on the down tube while the top cap is fitted. Sandwich the top cap firmly on the down tube and tighten the two 4 mm bolts.
Tighten the two 4 mm bolts tightly on to the BB cups.
Run the battery cable up the seat tube, securing it with zip ties. The SB50 connector should be secured just below the seat collar.
Run the throttle cable alongside the rear brake line up to the right side of the handlebar.
Add the non drive side crank arm and spindle. Make sure the spacers and the dust cap are on the spindle. Add the drive side bb dust cap and space.
Slide the freewheel chain rings onto the spindle with a little grease on the spindle.
Install the drive side crank arm. Make sure the crank arm is 180 degrees to the non drive side crank arm. Also make sure that the cinch fitment is lined up perfectly with the crank arm adapter grooves. Tighten drive side crank arm with 8mm hex wrench. Spin the cranks to make sure the BB is not overtightened. They should spin with no resistance.
Thread bike chain onto inner chain ring. This chain ring may be larger than the original chainring so check and make sure the bike chain is the right length for the new chain ring. Next thread the motor chain ring onto the outer chain ring.
Take the tensioner and preload the spring against the chain so that the built in stop is compressed to about 5mm from the tensioner arm. Tighten with a 4mm hex wrench.
The throttle is installed onto the handle bar. Some of the current shifters may have a tight fit. It is really important to not distort the throttle. Be aware that if the throttle is cantilevered from below by the brake attachment it will distort the throttle signal. Make sure the throttle springs back to neutral and does not get stuck on the handlebar grip, which may get pressed inwards on the handlebar and apply pressure to the throttle, restricting it's release to neutral.
HYPERDRIVE BATTERY INFO
HYPERDRIVE Vs E MTB / SUR RON / 125CC
Bridging the Power Spectrum
From analog bike (250watts) to emtb (500-750watts)to high performance (1500-4000watts) to moto (6000watts) the Hyperdrive can operate at all these levels. The power is set through a combination of battery choice (48-72 v) and controller power settings. From mellow performance to high performance.
Power to weight
This is the 'rare' air that make a Hyperdrive mountain bike so amazing! 176 watts per kilogram means light and powerful. That combined with the mountain bikes insane handling and suspension creates a bike that performs at 11X! It ushers in the era of 'Downhilling the Uphills'

BMS
The Batteries are made with the leading BMS (Battery Management System). This BMS self balances the cells in real time which is very important to the batteries health and comes with a great feature of being able to program and monitor your battery via a bluetooth app for your phone.
This app can be downloaded here: https://www.jkbms.com/support/
The download buttons for Android and Apple are on the right side of the page.
The password for the app is 1234
To program the battery the password is 123456
Please do not program the battery unless instructed to by Kranked as this will void the warranty.
To use the app:
Press Scan
Select your battery
On the Status page it will show you the current state of charge and the voltage of each series of cells.
Charging
We recommend keeping the battery plugged into the Grin Satiator charger at the 85% setting as the active BMS balancing slowly drains the battery and if it is not charged regularly can result in a battery that will turn itself off due to low voltage.
The Grin Satiator comes pre-programmed with settings to keep your battery in optimal performance. For 52 V batteries the default charge setting is for 85% charge at 1 amp charge. This slowly charges the battery (14 hours for a 85% charge). We recommend you keep the battery plugged into this setting between uses.
We recommend that an hour or so before your need to use the battery that you use the 5 amp setting to bring the battery to 100% capacity. This will ensure the best storage and use of your battery.
Charging - best practices
Keep the battery plugged into the Grin Satiator charger at the 85% charge setting as the active BMS balancing slowly drains the battery. If the battery is left off the charger it will slowly drain itself due to the active cell balancing it performs if it is not charged regularly. the battery will turn itself off due to reaching it's low voltage thresh hold. If this happens see the force start instructions in this section.
