Does this fit/sit on a bike rack that's attached to a hitch at back of car?

Definitely, it should be possible. I follow their YouTube channel, and there's a video that mentions what you're considering (https://www.youtube.com/watch?v=BOOyidzW4jA&t=3s). I'm planning to buy one and will try it out; I'll report back afterward

Yes, all electric bikes are now designed to fit most bike racks that attach to a hitch at the back of a car. However, I recommend checking the specific weight and size capacity of your bike rack to ensure a proper fit。

It should be possible. I saw someone in the comments mention that taking the bike camping looks pretty cool. I'm also considering this brand; I've been researching it for a month now, Finger on the trigger ...haha

Sure! A few months ago, I bought a Senada Saber and have already taken it camping, fishing, and for fun trips. The e-bike is very secure on the car's rear rack. I've only been riding it for a few months, but I already feel like a kid again!

Do these bikes have a throttle?

Yes, I see that all their models have a throttle. My brother-in-law has one of their Sabers, and I often take it out for a ride. It's very fast and powerful, so I suggest not pushing the throttle to the maximum—it gets too fast!

My archon has a throttle, and it's a half-twist throttle. I bought the Senada Archon this June, and without pedaling, the throttle can reach a maximum speed of 30 MPH.

Ebike noob here.. been wanting to purchase one. who is knowledgeable if this is a good deal and should pull trigger?

I'm not sure either. I'm also considering this, but I noticed they have a Black Friday sale, and it seems like the discounts during this event are usually quite substantial.

Of course it's worth it! I took a chance on a senada saber with a 21ah 48v battery over a year ago. Paid $1500 (ouch).

How loud is this when motors are being used?
Can I have a passenger sit on it? What is the weight capacity?

I'm not entirely sure about the exact weight capacity of the rear rack, so you might want to check with customer service. However, I have installed a child seat on the rear rack and often take my child camping. The rack is very sturdy, and I haven't encountered any issues so far.

Finger on the trigger …. can anyone comment on customer support or warranty issues and cost of extra battery?

I bought a Senada electric bike last year, and when I received it, I found that it didn't come with a battery. I contacted their customer service, and they responded quickly, sending me a new battery promptly.

A few days ago, I bought their Austin model, and before it was shipped, I received an email from customer service reminding me to confirm if the bike was suitable for my height to avoid any unnecessary trouble. I think they are very professional and considerate.

Had an issue with my senada peddle breaking off. Sent a photo and mailed me a new one with no issues.

What's a reasonable expectation for the life of a battery like this?

The battery life should be pretty decent. I got one for my wife around a year ago, and even now, it still holds a charge for her two-day commute. I'm thinking of getting one for myself now because it's way cheaper than driving. Fingers crossed, her e-bike battery keeps going strong!

I'm not sure. I just got my Saber last week and have charged it once. The battery seems to last pretty well, but I don't know how long it will last overall.

Looks like the breaks are wired disc's, I would be abit worried about the stopping power, anyone with experience on this?

I've already had saber for almost a year.I have not found the manual disk brakes to be an issue. I've never felt like I wasn't going to be able to stop in time.

Yes, spending an extra hundred dollars is definitely worth it. I recently bought the Senada Saber Plus, and they upgraded to hydraulic brakes. So far, I haven't encountered any braking issues, and the experience has been great.

If you're really concerned about mechanical brakes, you can check out their hydraulic brakes. I've also been looking into their electric bicycles recently. Seems worth it to spend 100 more for the 21Ah, with hydraulic brakes.

It's not that big of a concern. With the cable brakes, you might get some cable stretching over time but regular maintenance should take care of that. A well maintained brake, be it rim brake, cable disc, or hydraulic disc, will perform as designed comparably. There will be some environmental variance (as in wet conditions) between the types but all things being equal, they're comparable if they're well maintained. And maintaining cable brakes (both rim and disc) is easy.
