my wife's new electric bike [cannondale] is a load....

Well, it is very heavy... somewhere in the 20z.... but I have not weighted it yet.

Anyway, I'm assuming the battery is heavy component.

anyway, my bike shop was telling me the carbon fiber wheels can save a lot of weight vs. conventional wheels...

any thoughts in this? Would the difference in weight be small in relative terms?

Relative to the weight of the bicycle carbon fiber wheels won't make much difference. You are most likely looking at a pound or two max changing to lightweight wheels. Looking at Cannondale's electric bikes it looks like they weight between 30-40lbs. Most of the weight on an electric bike is the batteries and the motor, I have had friends remove the electric parts from their bikes (different brands) and that brings the bikes down to standard bike weights

After installing an e-bike wheel/battery kit on my AL frame commuter that has all the standard commuter stuff like rack, lights, fenders, trunk, dynamo, 35mm flat resistant tires, etc..it now weighs ~50 lbs. Consider yourself lucky that yours only weighs in the 20's. Putting mine up on the roof rack is a chore, even if it's a low Mini Cooper.

Oh, god no. Don't need carbon wheels on an ebike. You may save the weight equivalent to a small lunch sized box of raisins. That's nothing compared to the weight of the motor or battery. How much does it weigh?

+1 with above; save your money; the bike probably weighs in the 50 pound range (look at electricbikereview), and the difference with carbon rims would not be worth the investment.

My regular (100% human-powered) gravel bike commuter is 40 lbs with accessories and water bottle. Consider yourself lucky!

The battery and the motor are frequently 15-20lbs. Just for reference, a heavy wheelset is around 2.3kg and a light wheelset is about 1.5kg, so the most you could possibly save by upgrading wheels is 2lbs, that's not much of a dent considering most ebikes are 30+ lbs. Also, the higher speeds and heavier weight of ebikes mean that they're harder on wheels than a normal bicycle.

Depends on which Canondale. The $10K model is reportedly one of the lightest electrics ever made, in which case, the savings could be meaningful, especially if the stock wheels are one of the cost-saving (ja-ja) factors -the "conventional" range is quite broad. They probably did have to go cheap here and there to keep it at $10K, and still maximize margins here to compensate for declining sales elsewhere.

My Cannondale weighs 45 pounds!
No problem loading into roof rack..
The extra weight is well worth the enjoyment..

That model also uses a rear hub motor, so you can only upgrade the front wheel, saving maybe 200g.

Don't know how long you have been carrying your bike on the roof rack but just FYI a couple of teams in our tandem club have destroyed their VERY expensive rigs and in one case, caused extensive damage to their garage by forgetting the bike was on the roof when they drove inside. I always get a cramp you know where when I see someone drive by with a real beauty ($$$) of a bike soaring high above the road. Don't want to put the whammy on you but that's a real beauty you got there.
