I have been roaming this forum for the last month, searching for information how to convert my bike for work as a deliveroo coursier.
While there are responses for converting a bike for touring and commuting purposes, I have found little information for my own requirements and thus the reason for creating this topic.
Genesis tour de fer 30
Weight about 17kg
10SP rear , triple plate (I intend on reducing the rear to a 7sp and the triple to a double)
Disc brake, mechanical, TRP Spyke's
I built this bike up myself
Situated in the city of Grenoble in the french alps which is known for being one of the flattest cities in France, the surrounding parts are mountainous, and parts of the city can go upto 600m, although I will only need to deliver to 2 places where you need to go up. For the most part it is flat.
I have already owned a MTB Ebike with rear hub 250w that could reach 30km (it was stolen, Grenoble is also known for its bike theft..my 3rd bike within 5 yrs to be stolen haha). The bike had that horrible MTB flashy ebike look, no wonder it go taken. I found it to be a bit slow and didn't take into consideration my pedaling. I usually cover 50-80km in a day, doing on average 25-30km (19mph?) speed wise. Lots of start and stopping as you can imagine, between clients, restaurants, traffic lights, pedestrians etc. I'm looking for something that will reduce my fatigue as I do this normally 6 days a week, easily 300km a week in total.
Autonomy is therefore important as well as being able to achieve 30km p/h. As I do lunch and evenings, 3 hour intervals, I could recharge in between shifts thus allowing for potentially a smaller battery and therefore less weight.
What I have considered so far
Rear Hubs seem to be the most reliable, however I really would like something that allows me to pedal (assisted) and that does'nt have loads of drag when not functioning for example. I have read many good things from Mac 10t, Q100-128 36v, magic pie etc. Specifically I found a post from someone that was considering touring with a Q128 I believe, however I can no longer find the post to link.
Front hubs are the obvious choice for easy installment, however I am not phased by DIY. I fell off my bike recently onto a metal post, cracking my rib because the front wheel slipped whilst turning This makes me wary of front motored installation.
Most coursiers that use ebikes have mid drives that they rent out monthly, type Bosch, Yamaha. Bafang BB02 B seems like a obvious choice in this category 350w? or larger motor running it on lower wattage, not to sure. Tong shen TDZ2 was very promising, what with the torque sensor that takes into consideration pedaling and so a natural feel element, however reading the whole 72 page topic, it seems the motor may not be so reliable for daily usage.
Battery wise, because of autonomy, something large towards to 18ah seems feasible but as mentioned, I can recharge in between.
Mid drives allow me to swap onto my other bikes if I were to use this for other purposes, however, it is not essential as I could always use the same battery for different motors.
If there are any suggestions, please feel free. It would be nice to post up the finality to allow other people in the same predicament as myself to have a bases for a similar build. I have attached an image of my bike to animate the topic.
