7 years agoI really don’t understand why bike / motor manufacturers are not just putting 750W (ie max power motors) on every bike. The cost of the more capable motors is fairly small. My guess is that as battery capacity in increased with the new 21700 cells and or Li Polymer technology the bike companies will stop putting 250-500W motors on eBikes. In reality the federal regulation of 750W max has virtually no legal standing because both controller and battery voltage are part of the performance equation and it’s not like the police are going to have portable dynamometers to test if a bike is compliant or not.

7 years agoYeah, apparently in parts of Europe the police do have portable tools that can test in the wild. I have only heard this from one person but they work in the industry so I sort of believe them. I think in the US we are just getting what they sell overseas (in large quantities) but spiffed up a little to sound powerful or fast. In reality, I believe that a lot of the mid-drive motors are the exact same hardware, just overclocked a bit. Lower wattage means lower energy consumption and lighter weight (as is the case with the Shimano system especially) and I’m fine with that given my lighter body weight, range has never been an issue for me though and I’m a more active pedaler.

7 years agoHello Courtney; I really enjoy your videos. I notice that in several of your videos you mention the lack of water bottle bosses on many of the E bikes you review. Like you I enjoy having a bottle accessible. I recently discovered a product that many of your viewers may enjoy. Revelate designs, a US based company, manufactures a product called the “feed bag“. It mounts onto the stem of almost any bike and allows easy access to your bottle plus storage for small items. Eg. cell phone, wallet. It can also be easily transferred bike to bike. Check them out.

7 years agoThanks for the tip Pekka, it reminds me of chalk bags for rock climbers! I have seen massage therapists who use similar contraptions to carry around massage oil and stuff. This is a cool accessory and a great tip, thanks :)

7 years agoCourt,
Thanks for another fine review. My question isn’t specific to the Cero bike, but since it uses the Shimano STePs drivetrain, I’ll ask it here. The top assisted speed for this bike is stated as 20 mph in this review. However, the Shimano website states “All three support modes will assist until 16mph.” Can you provide any information about this apparent discrepancy?
ReplyCourt Rye
7 years agoHmm… you’re making me question my own experiences here but perhaps this is a geography thing. Like in parts of Europe they have a law that limits Class 1 electric bikes to 25 km/hr (which roughly translates to 15.5 mph). Maybe the resource you’re referencing is meant for that geography? I went to double check the website and indeed, saw the 16 mph reference here. Check out the Walleräng review video around 21:23 and watch for a minute. I film myself riding with one hand in the highest level of assist easily reaching 20 mph. So, unless Shimano has decided to tune-down their motors now or something, I think it’s a typo from their European spec.

4 years agoInteresting bike. What brings me pause is the max weight is only 270 lbs.
ReplyCourt
4 years agoYeah, it’s very unique. I agree that the weight capacity is a bit odd. It’s a cargo bike, so you’d expect 300lbs vs. 250 (which seems to be the standard for regular ebikes). I’ve seen some go all the way up to 350lbs, but 270 is kind of in-between. I guess they are just being conservative, and this appears to be a lightweight cargo bike vs. the full sized longtail ones. The team was really nice when I did this review, perhaps they have even improved the bike since then :)
