Batavus zonar e-go

[Ruben Correia]

Hi group, sorry to invade your group but I can't find anything about my bicycle,i live in Holland for all the cases,i have batavus zonar e-go and I would like to change my chainring to a bigger one, I move already the speed sensor to the outside and I install some magnets on the crank and I can go faster but I feel I pedal to fast when I drive at around 37km/h. I was at my local store and he told me I have 42t chainring already, I don't want drive 50km/h but I want pedal more comfortable at that speed. Also where I can buy all tools? Can I buy for cheaper, someone know something?

According to the spec sheet your bike has a Yamaha PW motor, any Yamaha or Giant ebike dealer ought to be familiar with working on your motor, or try asking in the Yamaha or Giant forums and say that your bike has a Yamaha PW motor. I’ve read that the Yamaha PW can mount a dual chainring so you would be better off doing that and getting a new front derailleur and chain to have gearing for comfortable pedalling up hill and on flat terrain.

changing the front chainring (48T) and rear cassette might help.
Look at the specs of this bike: https://www.haibike.com/de/en/ebikes/spedelecs/sduro-trekking-s-80-de826?id=4540504948
if you can find something similar, then you will be able to maintain higher speeds like 35km/h

Thanks for suggestions,i can drive 35km/h on flat road just I pedal to much, here in Holland its almost everywhere flat. I would like to maintain that 35km/h but without pedal that much. Someone know where to buy all tools and materials necessary?
