Build with Delfast Prime range?

[dmark]

I am a new Ebike commuter, enjoying winter-riding my Biktrix Juggernaut Ultra 1000 in Edmonton. The bike does not have great range (about 20 km with high pedal assist and some throttle, about 10 km with heavy throttle), but this is the exact size of my commute, and I am enjoying the ability to power through snow.

I ride a Rocky Mountain RC70 for summer commuting. I would like to summer cycle from Edmonton to Calgary (330 km). With a Delfast Prime (Hub drive, pedal assist or throttle, 380 km range), I could make it on a single charge. Has anyone built an Ebike with this kind of range? I don't care if if the bike is mid-drive or hub-drive, but I like the option of pedal assist or throttle like my Biktrix or the Delfast Prime. The Bike could be a conversion of my RC70 or one of my old 1993 Specialized Rockhopper/Stumpjumper bikes or a brand new bike.

The Delfast Prime was designed to go fast, but has a huge battery, so that a stunt rider was able to go 234 miles at a brain numbing 13.5 mph. The speed isn't what would numb me, but the 17 hours in the saddle at that speed. It had a 48V 64AH battery. That is 2592 watt-hours, so he used 11 Watt-Hr per mile. We don't know if he pedaled. I think he couldn't, in order to set the record.

I have a 52V 10AH battery that weighs 6 pounds. so the above battery must be around 40 pounds. It's not worth building a bike with a battery that large if you only need it for an occasional ride. I would suggest two batteries, and limit a days ride to that distance.

The smallest Juggernaut battery is listed as 48V12AH or 576 wwtt-hour, and your winter usage computes to 50 watt-hr/mile. I hope that's due to freezing temperature, snow, and maybe you're getting to work in 40 minutes (18 mph in snow?).

In the summer, on flat ground, my ebikes use 6-9 watt-hr/mile at 13 mph in pedal assist level 1 . Being a retired nerd, I have a wattmater to check that stuff. If it were me, I'd take 4 days to cobver 240 miles, so I think I could do it with a pair of 48V12AH packs. Charge them every night.

Drove thru Edmonton on the way to WHitehorse in 2008. Came in from North Dakota, so I stopped to see the big Easter Egg in Vegrevlle. Going home, we came back via Jasper to Calgary. WOuld you parallel highway 2 and take a small road?

I actually do ride fairly fast in the snow because I want to avoid fogging of my visor and glasses. I find that, on really cold days, it's best to go throttle only to cut down on fogging. I am building courage to go up and down stairs.

I wouldn't have any problem with a 40 pound battery. The total weight of my Ultra 1000 is 80 lbs (The battery is about 20-25 lbs.). The Delfast Prime is 95 lbs and my intended purpose would be to ride mostly in a straight line on paved roads. If I were to use one of my existing bikes (1993 cromoly Specialized Rockhopper/Stumpjumper or aluminum + carbon fork Rocky Mountain RC70) for a build, the starting bike weight would be about 20-25 lbs.

As for the route, the longest ride I have made is 100 km from Hamilton to Toronto on my nonelectric Rockhopper. In Alberta, I haven't cycled outside of Edmonton yet. My distance estimate comes from the shortest bike route from Calgary to Edmonton on google maps. If I ever get a good touring Ebike, I would like to go to Jasper and Banff as well.
