Thanks for the info - I was afraid of that. Any surfers out there know what a surfboard does to range?

When I tested my bike on my hitch rack the miles per kWh went from ~3.7 to ~3.2 for a 30 mile drive with 45-60 mph speeds. (80 down to 67 mile range assuming 21 kWh batt.)

More discouraging for the roof racks out there, I witnessed for the first time this weekend a driver forgetting about his bike on the roof. I heard a loud crunch and looked across the street to where a driver had driven into his hotel parking entrance. The bike was limply hanging off of the back of the vehicle and it and the rack were in shambles... I think this would happen to me if I went this route too!!

I've carried a lot of things on roofs including bikes. I always tape a note to the upper windshield with my height written on it. When driving towards something like a hotel overhang my eyes go towards the note.

I hate to admit it BUT----------I did this once to an expensive road bike. I worked a 14 hour day and totally forgot about the bike :cry:

Frame and wheels were trashed. I bought a new frame and wheels and transferred all components to the new frame. Cost was $1,500 for being tired and forgetting the bike on the roof of my 1957 classic VW ragtop sunfoof bug :x

VW, Yakama rack and garage door were fine :oops:

FYI - Yakima just released a new base rack system that is specifically designed to be very aero. It's called the streamline and you can find details here: http://www.orsracksdirect.com/yakima-ne ... -2016.html. The funny thing is that Yakima doesn't have it on their website yet and doesn't expect to for a week.

This thread has been quiet for a few years, but I'm hoping to get some more current advice. I just bought a 2018 Leaf SV and want to get a roof rack to carry my SUP. Any current info on what to look for/beware of when putting racks on the roof?

There are a number of premade that indicate they can be used on a Leaf. Would like to hear from anybody who uses a premade.

(These things are expensive!)

The biggest thing to expect is a pretty drastic reduction in range, especially if you are doing highway driving to get to your destination. Unfortunately, SportRack doesn't make a roof rack that fits the LEAF, so you're likely looking at a Thule or Yakama rack which, as you noted, are really expensive.

I totally agree with Alozzy, even if the roof rack itself is aerodynamic, whatever you carry is going to greatly reduce that.
Personally, if I needed more room I'd look into a receiver hitch with a rack to hold your goods. Trailing the Leaf it will be much more aerodynamic than anything you'd put on the room and gaining access it much easier than a roof rack. If you really really need more storage and want to carry heavier things then I might suggest a receiver hitch and small motorcycle type trailer. I've been eyeing up a couple real nice lightweight aluminum covered trailers that wouldn't add much drag(probably less than a roof rack) and you'd have easy access to things, heavy or light. They aren't cheap, the ones I'm looking at were over $2k plus the receiver hitch(several hundred dollars) but it could be used on multiple vehicles or by multiple people and being aluminum and covered, should last almost a lifetime :)

Thank you, Aloozy and jjeff. Let me just clarify on what you said : Do the roof racks themselves cause the drastic reduction or is it when they are loaded? I am glad to know to look for some that are aerodynamic. If the racks alone cause some reduction vs drastic reduction, it may not be a huge issue for me. I live on a small island (St. Croix) and since the 2018's get good range and I do very little highway driving, I may be able to live with some reduction.

I find the idea of a trailer very intriguing and since I'm no spring chicken, I like the ease of loading/unloading, but ... the cost! A workman recently ran over my SUP board so I have to replace it, too.

Whoops, my message was embedded as a quote, so here it is on it's own:
