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.

Incredible well made Ebike for a Great Price

First let me say that I normally do not write reviews but I was so impressed by this ebike that I felt like I needed to give a review to help others who struggled finding an ebike to fit their needs.

I searched for over six months researching ebikes and was beginning to have anxiety over what to buy. The fear of buying online vs a brick and mortar purchase. Generic brands vs name brands. Customer support etc. This is what my experience was with Senada.

First, the customer service is excellent. Being a nervous buyer I had many questions and Puckipuppy customer service responded to emails within 24hrs with answers to all my pre buying questions as well as after purchase questions. They were very clear and and super helpful. Tracking was provided for both bikes as well as tracking for the additional gift sets that I didn't even know I was getting. So a big plus for going up and beyond on the customer service.

Secondly - yes I am an novice with ebikes so I can only say what I have experienced so far. Both ebikes came packed incredibly well. They are arrived without even a dent in the box. Each bike took about 30-45 mins to put together.
Once assembled, I took each bike on a 3 mile ride through the neighborhood just to make sure everything was tight and working as it should then hooked both bikes up to let them fully charge before the initial real test.
The next day my son and I went on a 20 mile ride. Mostly streets, shared paths, and one short dirt trail. The bikes performed flawless. I am about 250lbs and used about half the battery on this ride. My son is about 175lbs and he used only used about 30%. Both of us used PAS 1-2 for the trip. There were some pretty good hills where I throttled up with the thumb throttle just because my knees were giving me some issues. I don't think this is a hard core extreme trail type of bike however, It totally handled the trail with ease and made the ride very enjoyable.
The bike does stand a little taller than I though it would so if you are on the short side you may have a little trouble at a stop or be better suited for a step through model.
Lastly - I am not affiliated with Senada in any way. I just wanted to share my experience with those that are having a hard time making a decision on an affordable ebike to enjoy with your family. Only time will tell for the durability but I plan to put roughly 60-75 miles a week on this ebike.

Best birthday gift ever from my children for my 50th

This bike is awesome. It has the speed, it has the endurance and it has the distance. I’m 5’9” about 220 pounds I’ve been driving around for almost a two weeks. And it’s like riding on a cloud suspension is great. Haven’t had the charged battery yet going about 27 miles on it, I’m testing it to see how long the battery will last I only drive it 2 miles to work 2 miles home and I’ve taken it out for a couple runs once in a while testing it when I first got it. Overall, I’m extremely Impressed first I’ve ever owned most likely looking to invest in another one for my wife.. The bike came shipped well and was very easy to assemble. And the onboard computer to let you know what’s going on very simple to understand. and one thing that I found phenomenal is the customer service I had questions they’ve called me back. They’ve kept in communication. I haven’t had any problems with the bike just a few questions , but customer service is top-notch.

Insane bike

Bought the Viper after 3 years of researching and looking for e-bikes. Well, this thing arrived in 3 days, very well packaged and easy installation. The bike is massive and a beast both on and off the road.
Looks fantastic in the snake pattern print and the motor is very powerful and responsive. I highly recommend this e-bike!

Wesley Parker
Very Impressed!!!

We received our Viper today. We assembled it (not hard at all) They even provided it with high quality tools to needed for the assembly. We did our first rides on it today for a total of 3.6 miles. It is very quick and has no problem with the hill on our street. I normally cannot ride my mountain bike up that hill without stopping and pushing. OK, I am old (69yrs). It pulls my 175lbs up the hill without any difficulty and even accelerates to 20mph while going up the hill.
I am impressed!!! and very pleasantly surprised!!

Valerie Gotts
Very impressive!

I love everything about this bike! I am very impressed with the quality and build. I have ridden a few of my friends e-bikes and decided to get my own. I paid half what my friends did for 3 times the bike. The suspension is top notch. You can't get a more comfortable seat. Customer service went above and beyond expectations. I have zero complaints.🤙🤙🤙
