The Duo Electric Longboard Kit:

THE ICONICALLY MODULAR BKB DUO

This is an easy to assemble, high-performance DIY electric longboard kit that includes all of the parts, tools, and tutorials required for assembly. Learn how every part of an electric skateboard works by assembling it yourself! There is no better feeling than riding something YOU built.

Specification’s:

6354 Dual Motors

• 160kv
• 3000W Maximum Power (per motor)
• 8mm Shaft with D-Bore - new pulley mounting system (no more set screws)!

Modular Drivetrain

• Our drivetrain is designed in house and is completely modular. You can use hundreds of different wheel types. The board will come stock with Flywheel pulleys, so any wheel with a genuine/clone flywheel core will work (ABEC11, Cloudwheels, etc). With a swap of wheel pulleys you can use any wheel with a Kegel core (Otang, Hyperdrive, Boa’s, TB110, etc). All of this can be swapped in and out in less than 4 minutes.

Duo Deck

• The 39" long x 9.5" wide Duo deck is made of Canadian Maple and fiberglass, making it strong and rigid. With a natural wood finish on the bottom of the deck, there's unlimited customizable possibilities!

LingYi ESC and Remote

• We utilize the LingYi ESC and remote to provide unparalleled performance and reliability. While VESC based ESCs are customizable, they are not as reliable as we need them to be. Everything is developed in-house at LingYi, so the remote connection will be rock solid and you will never have to worry about the ESC leaving you hanging. Plus it has all of the cool features such as roll to start, forward and reverse power, 4 riding modes, and much more!

Battery

About RailCore Battery & ESC Systems:
RailCore is our modular, quick-connect battery enclosure system. RailCore allows you to easy mount, or remove your battery with ease, along with being able to connect them in parallel! (3 packs maximum). The RailCore ESC and Batteries connect via XT90 connectors which slide together when mounting. Once you've installed your pin to lock in the modules, you're ready to ride! Then when its time to switch batteries you can do so in under 5 seconds. Or, you can leave them all on the board to charge at once. 

Battery Quantity:

The Duo 3.0 has changed E-board batteries from being a permanent decision to the most modular part of your board! Swapping, adding, and removing batteries are easier than ever, enabling you to have the perfect board for each ride. Please mind that range is dependent on riding style, conditions, and intensity.

RailCore batteries are built to perform. While they are just as capable on their own, a single battery may experience battery sag. Refer to this chart to have accurate expectations:

Battery (Quantity)	Battery Sag	Power	Range
12s1p (1)	Prevelant	1700W	6 Mi
12s1p (2)	Noticable	3400W	12 Mi
12s1p (3)	Best	4000W	20 Mi
12s2p (1)	Prevelant	1000W	15 Mi
12s2p (2)	Minimal	2000W	35 Mi
12s2p (3)	Best	4000W	60 Mi

Battery Size: 

We offer two different battery sizes, 12s1p and 12s2p. Both of these options have their own strengths, which we will highlight here to best gauge your options. All specifications below are for 1 battery. If you have 2 or 3 batteries in parallel you need to double or triple the values accordingly. 

Battery	12s1p	12s2p
Range*	~6 miles	~15-20 miles
Weight	2 lbs	4.75 lbs
Dimensions	160 x 160mm	160 x 160mm

*Range estimations are with 97mm wheels, 170lb rider, moderate speed, and moderate hills. Actual range is hard to predict and highly dependent on on your weight, temperature, elevation gain, wheel type, and riding style.
