Why did you converted the Alfine 8 hub to an Alfine 11 hub, and what exactly do you mean with: will bog the motor down?

There are barely any Shimano Alfine 11 ebikes and they are very expensive. Basically all the belt ebikes have the same setup, except if they have a Rohloff hub or a Shimano Nuvi 360 hub. The plan was to avoid a derailleur setup, because of the maintenance in the winter.

To be clear, this topic is not meant for tuning, the Bosch ALP engine is a low resistance engine, hence if you cycle over it's support, it will feel as a normal (heavy) bike. Only for that reason i want to adjust the gearing setup. I'm planning to buy the SG-S7001-11 hub, it should have an improved performance for both E-BIKE and non-E-BIKE usage. https://bike.shimano.com/en-EU/product/component/alfine-s7000s700/SG-S7001-11.html

I'm planning to buy an ebike with the following setup: - Bosch Active Line Plus - Nexus 8 - 125T Gates CDX Belt - 50T sprocket front - 24T sprocket rear I'm not quite happy with the gearing setup, i want to decrease the required cadance to go beyond 25km/h 2 options: replace the sprockets or replace the hub. Replacing the sprockets is questionable, i'm not sure yet which sprockets will fit, i have to respect the required center distance. I don't know the minimum and maximum available center distance of the ebike. Hence, replacing the Nexus 8 Hub with an Alfine 11 hub will always do the trick. Question, is this doable? Is it a lot of work? Are there any points that require extra attention? I've never done this, so it will be a mini project.

I'm wondering if Bosch could detect this: https://www.pedelecs.co.uk/forum/threads/diy-mechanical-dongle.34683/

I'm trying to decide between one of the below bikes as a daily cycle for home-work distance. Both have their advantages. Winora Sinus iR8f Bosch Active Plus Nexus 8 Gates belt 500Wh Pegasus Opero Evo 10 Shimano STEPS E8000 Deore 11 speed derailleur 750Wh (2x 375Wh)

Then the comparison is not fair, because of the pedal resistance.

Are your bikes tuned? Or where you simply cycling till the 25km/h limit? Because then it makes sense that on flat gradients you are much faster, because above the 25km/h you don't have any pedal resistance.

Thanks, and how is the battery life with the e8000?

It is probably a cheaper engine to buy.

I'm planning to buy an ebike with a Shimano Steps E8000 motor. As this motor is restricted on 25km/h and i often want to cycle faster than 25km/h, it is important for me that the motor has no resistance. Does anyone know this? I know that the Bosch Active Line Plus has practically no resistance, i hope that this is the same with the E8000 motor.

The police in my area is selling a ebike that they found in a ditch. It's an ebike from 2017 with a Yamaha PWseries motor, they don't know if the motor + battery will still work. It's an auction, so you have to bet on it. The bike itself looks quite oke, only some screws are a bit rusty. What do you think, can a Yamaha PW motor + battery stand that much water?

Sorry, i mean 30-35 km/h and derestricted. It almost looks if the ALP is a far better motor than the CX. The CX is powerfull and that's it. No other benefits. I'm not sure if you ever tried the CX motor, but peddling harder than the engines support is not really doable.

Thanks for all the advice! Suppose, hypothetical speaking, you want to cycle between 30-35km/h. Which motor will be the most efficient motor, the Active Line Plus, or the Performance CX? And why

Which motor would you prefer for travelling between home and workplaces in a flat country? (Tuning is possible) Bosch Performance Line CX Pros: - Powerfull, maybe therefore also a long durability - Up to 120 cadance support Cons - Not efficient - Without support, a lot of resistance - Noisy Bosch Active Line Plus Pros - Efficient - Quiet - No resistance Cons - Less powerfull - Up to 105 cadance support

Thanks! Will the 35E Samsung cells also drain faster with a TSDZ2 motor? Will i notice that my battery level will drain faster than with GA cells?

Thanks, that is helpfull. I'm planning to buy the TSDZ2 or the BBSHD motor. TSDZ2 Controller = 18A max 18A/5 = 3.6A BBSHD Controller = 30A max 30A/5= 6A Based on the specs, I probably wouldn't notice a significant difference with using the Samsung Cells for the TSDZ2 motor? But probably i will do for the BBSDH motor? Hence, would that mean that with the BBSDH motor the Samsung cells would drain faster than the Sanyo Cells, but with the TSDZ2 it is almost the same?

Thanks, so on the 2,3 and 5a the Samsung and the Sanyo's are quite close, the difference starts at 10a. Now i'm trying to understand what it means. When is it important to have a straight curve at 10a? In case it depends on the controller, for everything under the 30a, the Samsungs are ok, else pick the Sanyo's?

I'm searching for a nice 52v battery for my ebike and i'm trying to decide which of the 2 below batteries is the best buy. The price difference between the batteries is 100 euro (€ 392 vs € 492). They have the same voltage and Ah spec. The other difference are the cells. the cheapest battery has the Samsung Cell and the other battery the Sanyo Cells. I couldn't find reviews about the Samsung cells, the Sanyo cells are well rated. Now i'm wondering if the Sanyo Cells are really that much better than the Samsung cells. Can someone advise me with this decision? Sanyo NCR18650GA 3.7V 3450mAh 10A 3C Cells Samsung 18650 3.7V 3500mAh Cells

I'm planning to build my first e-bike but i'm doubting between 2 engines: the TSDZ2 or BBS02B. I like the idea that when i press harder the TSDZ2 engine will support you more (superman legs). However, as i will be use it daily i have my doubts if it the smartest decision as not the best materials are used for it. The BBS02B engine is more robust, has more torque but it works with a PAS system. If you don't know any better i believe that in general most people will like it. What is the best choice, does anyone have experience with both the engines, preferable long-term. To power the engines, i'm planning to buy the Hailong E-Bike 48V 17.5Ah battery.
