    Bosch Performance Line Motor

    Bosch lists eight Performance Line motors. All are 250-watt nominal, 600-watt maximum, and torque rating ranging from 55Nm to 85Nm, which is meaningless because they don't tell us how they measure those numbers. In general, I have found Bosch motors to be wimpy compared to Yamaha motors. Those...

    New year, new cargo ebike

    I have been riding a Yuba Spicy Curry AT (all terrain) cargo bike for the past two years. It's a good bike, although a few improvements would make it really good. The good: front suspension, seat-post suspension, 2-inch plus tires, dual battery option for 80-100 mile range. Bosch Cargo Line...

    Used Crosscore RC

    Yamaha's are good bikes. I really like the Yamaha motor of my 2016 Haibike AllMtn. That said, with any used ebike you should be concerned with the health of the battery, the most expensive part that consumers can replace. (Yamaha won't sell motors directly to consumers.) Since the charger is...

    Do cell phone holders damage phones?

    I also like the ability to attach a GoPro camera to the front of the Peak Design mount while the iPhone is facing to the rear. I have PD mounts on both my ebikes. I also use a small PD accessories bag on my Jones H-bars. And I have a PD car mount, PD camera leashes, PD camera cubes, etc.

    Tern S10 or Qualisports Dolphin?

    @An_Professional, go with the Tern Vektron S10. It is a quality bike from a quality company that has many dealers across the country, including REI. If you ever need service, parts, or advice, having a professional network available is invaluable. We owned a Tern HSD S+, a great bike that gave...

    Poll - Did you upgrade from Cadence Sensing to Torque Sensing?

    I beg to differ. From Bosch: "Drive units from Bosch eBike Systems give you a unique riding sensation. Three sensors measure the rider's pedal power [torque], cadence and speed over 1,000 times per second." From Yamaha: "The center mount drive and triple sensor system delivers outstanding...

    Poll - Did you upgrade from Cadence Sensing to Torque Sensing?

    It does not have to be either or. Both my bikes, a 2016 Haibike All Mtn with a Yamaha motor, and a 2022 Yuba Spicy Curry with a Bosch motor, have BOTH cadence and torque sensors. I may be wrong, but I believe that is the case with all the current offerings from Yamaha and Bosch. (They also have...

    anybody have riding videos?

    I have years of footage but don't have the time to edit, although I have the skills and the tools (Mac with Final Cut Pro). I began riding ebikes in 2016 and soon attached my GoPros to my bikes. I would record nearly every ride, and I ride four times a week, 20 to 40 miles per ride. I thought...

    Do most speed sensor systems use a magnet that's mounted to a wheel spoke

    Both my Haibike and my Yuba ebikes use a magnet mounted on a wheel spoke. I've owned the Haibike since 2016 and and have over 15,000 miles, on and off road. I've had the Yuba for 18 months, on and off road, riding it four times a week. No problems with the magnet on either bike whatsoever...

    Current etrike offerings and buying tips

    I have been waiting for Arcimoto to produce their Lean Mean Machine ever since they bought Tilting Motor Works, purveyors of motorcycle conversion kits that convert certain Harley, Indian, and Honda motorcycles into tadpole (two wheels in front, one in back) trikes. The tadpole configuration is...

    Do you carry an extra battery?

    I carry two batteries on each of my two 36V torque-and-cadence-sensing mid-drive ebikes. My 2016 Haibike AllMtn came with a 400WH Yamaha battery, and I bought an extra Yamaha 500WH battery two years ago. The original 400WH battery still has about 90% capacity after about 14,000 miles, and the...

    Dual Battery Balancer circuit - experiences!

    I know, @Ravi Kempaiah, that you asked for experience with high-voltage (52V) dual batteries powering hub-drive motors, so my experience is not directly relevant. I have been riding a mid-drive Yuba Spicy Curry AT with two batteries for the past 18 months. It is a Bosch system. A 36V system, if...

    Help finding a mid-drive, torque ebike with a throttle and natural pedal assist?

    Back to trying to help @tricycle with his request, Jeff Jones makes ebikes with Bafang mid-drive motors, throttle included. Spendy, but @tricycle did not mention a budget. Jones has a wait list, so it may be a while before you can get your hands on one. Apparently, he prefers to talk on the...

    Best wind noise solutions?

    One alternative is to wear musician's earplugs, i.e. earplugs that attenuate all frequencies evenly but still let you hear all the sounds around you at a lower volume (usually 20dB lower). Although I don't use them when riding, I use them on other occasions.

    Tern HSD gen 2

    We owned the gen 1 Tern HSD S+ (the one with automatic Enviolo drive and carbon belt) and enjoyed it a lot. It's main drawback was its wimpy Bosch motor with only 65Nm of torque (which, I feel, was an exagerated figure). It's good to know that the gen 2 HSD's now have a more powerful motor, but...

    How's the bike infrastructure where you ride?

    Jeremy, thank you for starting this thread. With all due respect, however, as a resident of San Diego since 1975 I have to disagree with your optimistic assessment of our bicycle infrastructure. I would give it no higher than 5/10. Yes, there are separated bike paths along the San Diego River...

    Tern HSD to GSD

    Yes, I forgot that the 2020-2021 HSD's with only 50Nm of torque was called the Bosch Active Line (not the Performance Line). I edited my post above to reflect that. It appears that some (but not all) current HSD's models have the Performance Line motor with 65Nm of torque. Still, the 85Nm Cargo...

    Tern HSD to GSD

    In 2020 I bought my girlfriend a Tern HSD S+. She liked it a lot and rode it frequently until last year. (She decided to stop riding bikes because of the danger of breaking bones due to osteoporosis.) I rode the bike occasionally and my disppointment was primarily the wimpy Bosch Active Line...
