Surprised the new neuron felt the worst, I considered a lightweight model. Quite glad I went full ebike. Though I still think lightweight ebikes will be the future of ebikes. Just probably be very expensive.
Nearly everyone seems to go full ebike at least on MTB forums.
I don't get how the tiny weight savings are worth it.
Bosch SX is 2kg
Bosch CX is 2.79kg
saving an amazing 0.79kg on the motor, in percentage terms it's huge but in reality come on? is it worth?
750wh tube battery is 4.3kg
400wh compact tube is 2kg + they seem to come with the 250watt range extender which weighs 1.5kg...
0.8kg on the batteries but have 100 less capacity, drop a 625 weighing 3.65kg in a full fat bike, never ride full power and your basically mostly a light weight ebike anyway?
if light weight motors become a thing it's because it's forced with no other choice, purely to save money.
the most reliable Bosch bikes according to thebearingman were the early full fat motors because they were over engineered, with a rubber seal kit they last forever.
as CX got lighter they also got less reliable parts fitted inside, the SX light weight motors how long will they really last? how reliable are they?
to me I don't see how the tiny weight saving is worth it, maybe if your 60kg to you its huge, but as a big bloke it's barely a few percent of my body weight
pedal strike on a full fat slightly worrying, pedal strike on a light weight motor? not for me, I'm out
On light weight you need to pedal at higher cadence than on a full fat to get the same power output from the motor btw
with a SX it only outputs 600watts peak power at 100+ cadence.
Bosch own website has the text
The Performance Line SX is significantly more compact in design and lighter in weight. Due to the lower torque, however, it requires a higher cadence to achieve the same support
not worth for the weight saving...
100cadence
might as well be on a analogy bike spinning up that hill.
SX must get hotter than a CX at the same cadence then when the motor is struggling to give enough torque, so the motors performance drops off to prevent overheating, the motors also smaller and contains less metal so it's less effective as a heatsink
also text from Bosch own website
For eBikes, we distinguish between
rated continuous output and maximum power. Maximum mechanical power (also called peak power) describes the maximum power that the motor can call up for a short time under optimal conditions (e.g. sufficiently charged battery),
for example on climbs.
The duration depends on several factors, such as the cooling of the eBike components, the charge level of the battery and the outside temperature. By calling up the maximum power, the eBike components continue to heat up, which means that the maximum power cannot be called up permanently to protect the components.
Hopefully this puts anyone off buying one
a lot of people buy their kids Ebikes though including full fat ones, so I guess theres a market for them.
