Hi amberwolf. My take on Tig Cross's description of the Electrom is the chain to the rear wheel is set to an optimum low gear (can't change that ) and there is no gearing to change on the generator side because there is no need for gears.

Hi amberwolf. You successfully identified my reasons for inquiring into the SHD; recharging at stops, constant cadence/loads, not having to shift gears on the pedal-chain system, simplify the drive-train layout to the rear swingarms of my tilting delta velo. I am looking at three options. Plan...

Thanks amberwolf. So a 323w output in a parallel system results in approx. 88% efficiency-vs-81% (fetcher's calculation) and possibly 7.2% less for the series. This is the quantitative stuff I've been looking for. Thanks. Would it be correct to say that the Electrom's blend of a direct chain...

Hi fechter. Your reply is helpful. It's the quantitative data which will help me decide which route to go. Just wondering, would you consider the following claim credible? A SHD is just a few --? percent less efficient than a PHD. What conditions or qualifiers should I be looking at within this...

Hi Grantmac You are correct, even Andreas Fuchs admits that the efficiency of a SHD cannot compete with a purely mechanical-drive bicycle. But he does claim that SHD is comparable (a few % lower) to peak efficiency of a Parallel Hybrid e-bike. Here are two examples of commercial Electronic...

Hi amberwolf Thank you very much for the link. I have viewed videos of the Electron on You tube, but the the info in this forum is far more helpful to my interests. I am trying to identify the most suitable electrical components as well as the design features which would apply to my tilting...

In his article- Series Hybrid Drive: Advantages for Velomobiles-, Andreas Fuchs states that velos are ideal candidates for SHD Systems. The velo's slow acceleration and climbing is well suited because the pedals of the generator accelerate fast, gear changes are almost instantaneous, thus...
