Weight of Battery and Seat/Seatpost?

[FloridaNative]

Title says it all... looking for the weight of the battery (by itself) and the stock seat/seatpost assembly as a unit (but separate from the battery). I am trying to determine how low I can get the weight of the bike for traveling (with both wheels on).

Thanks,
Mike

What is the bike? Post some photos. Normally batteries have nothing to do with a seat post.

Lectric XP (either 1.0 or 2.0, regular or Step-Thru, doesn't matter). On order, I don't have them yet. Correct, batteries have nothing to do with a seatpost other than they are both easily removable for transporting the bikes!

Thanks,
Mike

Looks like you want to remove the seat and battery from the bike before mounting it on something like a platform carrier?

Platform carriers have been beefed up over the years and can accept as much as 90 lbs. PER EACH ebike, so no reason to remove the battery and seatpost.

I disagree with most of that. First, you have a good guess but we don't know why the OP wants to know the weight of the battery and saddle/post. Then there are certainly more platform carriers that can handle heavier ebikes than there used to be, but you have to be willing to pay for one, be careful to pick the right one, and your car needs to capable of handling all that weight. 1 1/4" receivers probably won't work for that much weight. Of course we just don't know, but the OP may already have a rack and be close to its weight limit. Or he may be shipping his bike by truck or by air. You sure can't assume that a platform rack will handle two, or even one, 90 lb. bike just because it's a platform rack.

Second, even if you have the right rack on a HumVee, it's a safety and security risk to leave your battery outside on the rack; I guess just a security issue for the saddle. I have a vehicle/rack that will handle the weight, but I would always want my battery and saddle off the bike and in the truck.

Yes, it’s so I can carry them on a hitch-mounted rack. I already own a rack, but it’s not rated for as much as the bikes will weigh. I’m trying to figure how much the bikes will be over weight and if I want to risk that or not. I will probably break down and shell out the extra money for a beefy rack, but I just want to have as much info as possible before I do that.

And it gives me something to think about while I want for our XP 2.0s!

Thanks!

Glad I was able to guess what you needed

I understand what you are going thru, because half the racks I flip go to ebike owners.

Another good reason to remove accessories, flashlights, lamps, seatposts, batteries, while the bike is on a platform carrier is to reduce stupid theft. People can and will steal anything for any reason at all. A security hitch cable will indeed secure the frame and wheels, but not everything else.

Batteries can be pretty heavy, but if you're worried about pushing the limit of your hitch or rack capacity, in my opinion you need to get a heavier duty rack or receiver before you start calculating whether removing the saddle (and post) is going to keep you under your max weight. It's a peace of mind kind of thing. You'll feel a lot better about selling your old rack on Craigslist and getting another rack with at least about a 10% to 20% buffer over what you expect to carry.

Batteries can be heavy. Removing the batteries might get you under the limit but that's like winning on a technicality. I think you really want to have more of a comfort zone for dealing with potholes and other big bumps.

To mostly answer the original request of weight of battery and saddle (minus the stock seatpost) here are pictures with the weights in imperial and metric. The battery is the original 10.4 AH with LG cells from my XP 1.0 and the saddle is also the stock one minus the post. I can remove the stock seatpost to weigh it if needed but was hoping this would suffice for anyone who wanted estimates.

Thanks! Much appreciated! Looking at the Lectric website, a suspension seatpost weighs in at 1.1 pounds, so I would figure on the standard seatpost to be a bit less, so looks like:

6.5 pounds (battery)
1.5 pounds (seat)
1 pound (seatpost)

Which means one could shave about 9 pounds off the bike pretty easily if needed (getting it down to about 54 pounds).

Thanks all!

Rain is one reason to remove the battery and seat. Lifting aheavy bike onto a rack is another. The owners manual even says to remove the battery. I can't think of a single good reason to leave them on a bike being transported if you can easily remove them ...

A battery left on the ebike protects the contacts on the ebike from rain.

Most seats are weatherproof (not leather), removing that and you risk water pooling into the bike frame.

I would say yes usually, but the Lectric XP has an internal frame battery, which would not have this issue.

I don't ride an XP, but I would still remove it and cover the battery opening, any non removable display, and the seat tube, as most on here do anyway. I have a hi top van and transport everything inside the van, so far.

You could get a small utility trailer cheaper than some of the heavy duty racks.
