I feel like my search keeps expanding , I need to come up with top three reliable fast short commute choices under 5k
So I have been researching e-bikes for around town commuting and fun on local trails in Bellingham, Washington which is a rather hilly spot. I have taken test rides on 14 bikes from Kalkhof, Rad, EMotion, Bulls (3), Focus (2), Cube (3), Riese & Muller(3). I have read and watched the video reviews on this site for all the above and at least another dozen more. I do have a bias in favor of German engineered vehicles and have been driving a Mercedes wagon for the past 25 years, currently an e500 4matic wagon.
After lots of careful consideration, I put an order in for a Riese & Muller Nevo Nuvinci GH It comes with the Bosch CX they also have an HS (high speed) with a Bosch Performance motor. They are just under $5000. Riese & Muller bikes come very complete as regards accessories (lighting, fenders, locks, racks) as well as really top flight peripherals (brakes, tires, rims, drive systems, grips, saddles, suspensions, etc.). Build quality is outstanding, designs are interesting and well thought out, engineering seems to be thorough and complete.
I tried both the CX and the HS models in both Riese & Muller as well as Bulls. I found that the CX higher torque performance on hills is something I would be making good use of all the time, whereas the HS version while capable of going up to 28mph with power assist, requires a lot more pedal effort past about 22 mph due to exponential increase in wind resistance...enough to make me less eager to go that fast, especially when it means sacrificing hill climbing ability.
Right after ordering the Nevo, I ended up getting a smoking hot deal on ebay for a really nice Cube (another German brand) so that is what I'm riding now while I wait for the R&M to be delivered. Then we will have two nice bikes for my wife and me to go riding together.
The Cube is great but the Riese & Muller with the Nuvinci drive and Gates carbon fiber belt drive is a very clean, low maintenance option that has a ton of appeal to me. There is some efficiency loss in the Nuvinci drive so you might want to look at the GT Touring models from them as they have traditional gear cassettes and derailleurs. That will give you less frictional power loss for that extra little bit of oomph.
Count on it taking on month minimum, unless you are lucky enough to find a dealer who has just what you want. They offer lots of options and produce them in Germany to your specs. Add in cross Atlantic shipping, dealer set up and delivery an you have a wait that will try your patience. From all reports well worth it though.
Let us know what your decide on.
