There has been a lot of good development over the past 10 years in energy storage, and a lot of 'break-throughs' that go nowhere. However, these two newer advancements could be real, and not only for EV's, but aircraft and robotics as well...

https://insideevs.com/news/446430/video-tesla-battery-day-phd-scholar-ev-researcher/ I love my ST2, but I also follow several EV sites, and its really fun to see the cross-over in technology between bicycles and cars (planes and boats). But, this was especially exciting to see the recent...

I follow EV's as well as eBikes, and found a great presentation from Ravi Kempaiah regarding current energy storage technology. I know Ravi can be a bit humble, but this is really fantastic! He does a great job of breaking down each area of the technology, including full life-cycle of the...

Battery Technology continues to update, however motor improvements have minimal. This is just a recent article noting some nice advancements in axial flux motors, which might have an application to direct drive hub motors for eBikes. Weight an efficiency are two drawbacks to rear hub motors...

This is exactly where the conversation should go. Road infrastructure, both highways and interstates, are in great need of replacement. EV's and autonomous vehicles will be at the table to help create the vision for smart road design. As eBike enthusiasts, we need to understand the...

Great design for the ST5! If they could have included the Pinion drive, it would been even better (ultra smooth/quiet). I'm sure they're working on it. The other feature that no eBike has (that I'm aware of), is rapid recharge. If Stromer could get their battery to recharge in 20 minutes...

Thanks for the news, glad to hear that Stromer is continuing to innovate! I much prefer rear hub motor vs mid-drive. The ST2 is a very advanced cycle, and I love mine. The three areas to improve: Motor, batteries, and chain-drive. If the motor is new, hopefully the design can be...

Very good points, and we'll have to watch the process as it unfolds. However, wasn't the argument for s-pedelecs (28 mph), that a well-conditioned bicycle rider could maintain these speeds on a standard road bike? If that is the case, then the argument for more regulation would be to limit...

I'll watch the video this evening, thanks! Yes, the dreaded rear hub-motor/flat tire challenge (the only real flaw of the hub-motor design). Funny you should mention this. I had a few rear flats on my ST1 elite, then added a tire liner and Slime tube. I wanted to see how good the Big Ben...

Thanks! Is your assessment that battery technology will be a gradual evolution of Li-Ion, or do you see bigger leaps over the next 10 years?

Hello Ravi, thanks for your response! Glad to hear that the motors very similar, with the removal of the controller the bike is much more balanced, and the heat dissipation is greatly improved from the ST1 (I also have an St1 elite). I purchased the ST1x with the 814wh battery, and will be...

Thanks for your excellent research and post! I received my ST1x in April, and will post the my thoughts later this month after I put on a few more miles. Is it known whether the Cyro Drive motor is the same as the Syno Drive motor? I haven't been able to find specific information on the Cyro...

Just thought I'd ask, but is the answer the same for the ST1x?

Thanks for the tip on the Omni lock mode! A couple of reasons that why I went with the ST1x. Originally I was set on purchasing the ST1 Platinum, and was quoted at a very favorable price, which was hard to turn down. Unfortunately, I have not ridden the ST1x but ordered it anyway based on a...

Thanks, appreciate your thoughts! The ST2 was not in my price range, however I'm looking forward to longer rides and upgraded the battery to the 814wh. I've ridden the ST1 Platinum, but not the ST2. What's your opinion riding hills. Big difference, or very similar?

Hello, I've been a forum member for a couple of years and really wanted to thank the community for all of their input and knowledge regarding ebikes and specifically Stromer! Also thanks to Court, his reviews and videos are the best on the web! Having owned a Stromer ST1 sport for a few...
