VIPER comes about 95% assembled, there are some final assembly and adjustments needed, like the front wheel, the handlebar, the seat, the pedals, the headlight, the fenders, and the rear rack.

For any assembly questions, you can download the instructions on our website, or, contact our support team via

There is a quick release skewer for installing the front wheel, place the front wheel on the wheel hub, then tighten and lock the quick release skewer.

There is a spring on each side of the quick release skewer. The small end of the spring is inward and the big end is outward. The nuts on the front wheel do not need to be removed.

In addition, please make sure both sides of the fork is clipped on the hub, not on the quick release skewer.

*Please check the tire position before and after inflating the tire, inspect the wheel to make sure the bead seat line is aligned to the rim, the bead is uniformly seated and the inner tube is not poking out from the underneath of the tire.

1. Look for the “L” or “R” sign on the axle or wrench flat.

2. The left pedal needs to tighten counterclockwise, the right pedal is tightened clockwise.

3. The thread of the pedal and crank arm needs to be aligned carefully, if the thread is misaligned, the crank will be mangled or cross-threaded.

4. It is suggested to tighten the pedals with a pedal wrench, and use some anti-seize compound if have.

The front fender and the headlight share the same set of bolts and nuts. Here is a video guide on how to assemble the fenders, headlight, and rear rack:

Install the rear rack on ARCHON:

1) Install the fully charged battery on the bike;2) Insert the ignition key on the right side of the handlebar to turn on the power;3) Long press the M button on the display to turn on the system;

4) PAS 1 or 2 is the recommended starting speed (PAS 0 means no motor assist);

5) You can now ride the bike by using the twist throttle or pedals (with power assist).

Please follow the steps or video below to change the settings:

1) Long press '+' and '-' at the same time to enter settings;

2) Press 'M' till the display shows '02' (mileage unit);

3) Press '+' or '-' to change it, '0' is KM, '1' is MILE;

4) Long press '+' and '-' at the same time to save and quit the settings.

One set of key (smaller) is for ignition on the right side of the handlebar:

The other set of key (bigger) is to lock/unlock the battery on the bike, it is wrapped with foam together with the battery.  

Each key set has two same keys, we suggest you keep one on each at home just in case.

I haven't opened the box yet, but I am so excited. Can't wait!!

I received an email for 100.00-dollar discount on my first purchase, but have not heard anything back when I sent an email requesting the discount since I forgot to take it off at the time of purchase?

Jay Smith
Senada / Viper

I love it except I want to add a bigger sprocket on the cank, and the shifter to match. And since I ride more street than trail I am thinking a more streetable tire. The stock ones are so soft I already had 2 flats and it's a little hard to steal because of the softness of the tires.

Philip Herrera

Very satisfied 🚴

Wesley Allison
Great bike, mostly.

Great full suspension E Bike. Powerful 1000 W motor. Received my well packed e-bike in a huge box. It only took 20-30 minutes to assemble. This bike is built well. I was so surprised on the power and speed on my first the test ride. I was like a kid in a candy store. This bike is awesome! All my friends are sayin', that bike is BADA$$!

Kenneth Martinez
Good Value

I highly recommend this bike to any hunter. It's a great investment that will drastically improve your hunting experience. Plus, the customer service team is very helpful and responsive. They helped me choose the right bike for my hunting needs and were very knowledgeable about their products.
