i could be wrong but I’m guessing you would remove just one link by going from 20t to 18t
I have a 15t and am happy with that. Any bigger and I would struggle to climb really steep hills even in the lowest gear
I really think the Bosch powerpack looks like something from the late 70s or early 80s
It reminds me of those early mobile phones. Even the carry handle looks like a silly antenna.
In years to come humans will look back in disbelief and ask did people actually pedal around with a giant brick...
the problem with IC MTBs is that they would be phased out in a few years due to government regulation.
Then we will have no alternative but to buy an e-bike which will use lithium ion batteries and have a range of about 30-50 miles.
I really can’t see these e-bike contraptions catching on...
