Doesn’t your Zen Photon Ultra have a M620?

I have the Garmin 830 that I swap between my two e-bikes - one with Garmin’s speed sensor mounted on the rear wheel hub, the other without a speed sensor. It will automatically use GPS speed if it can’t detect a speed sensor. FYI the speed sensor needs to be added to the sensor list for the 830...

Chain is stretched or wrong chain. Doesn’t even look like the KMC chain is their e-bike rated chain. Which I don’t rate that great anyway - stretched mine in less than 800 klms. Compared the sram gx chain on my other 1800w eMTB which is still perfect after 1200klms.

Range, power, torque and speed.

Frey uses the Bafang Ultra motors in their bikes with throttles. I doubt the smaller light weight mid mount euro motors could handle the thermal loads generated by a throttle.

I very much doubt any other bike shop would do that for you unless you bought the bike from them as a dealer of that brand of bike.

Why don’t you go to the bike shop you bought it from and ask them to lift the limiter? I’m pretty sure it’s only a setting in the display which is passcode protected.

No manufacturer makes anything that lasts 10 to 15 years any more. It’s just a bad business model to do so. Figure on 5 years…..7 years tops.

I don’t blame you. In my opinion, having the limit isn’t worth the extra spend over a traditional bike.

Per their specs that is the lowest rated torque figure which might be for the 36 volt version. There are also 48 and 52 volt versions which i suspect have the higher torque ratings of 120/135. I have the 48 volt version in my hardtail e-bike and it’s a fairly grunty motor and will reach...

I’m in Australia too and yes the speedo works properly.

New Ananda m300 has same mounting points as the m100 that can rival the Bafang m620 for torque at a lighter weight - 2kgs lighter.

The m100 is a great motor - I have the 48v version. Not sure if it can be swapped for the m510, but why would you want to? Mine is also in a hardtail bike that I use to commute to work after swapping the tyres, grips, and upgraded rotors and pads.

Yes I believe the m630 was intended for that purpose. I have the 60volt version of the m620 which goes well.

I have two e-bikes. One powered by an Ananda m100. This was derestricted by the dealer LBS at purchase and still covered by warranty. It tops out at 47klms/hr assisted, though I have pedalled beyond assistance to 55klms/hr. No issues after 16 months. My other bike has the Bafang 60v m620 which...

I agree. The m620 already has more than enough torque and speed. It also has a more progressive curve based on the comparison graphs. The m630 might be best suited to cargo bikes or bikes pulling a trailer coupled with the matched 5 speed auto.

Does the wife know where her missing cooking appliances are? 😳

Agreed, which is why I suggested fitting the biggest chainring you can physically fit. Spreads the gearing between shifts and keeps you in the bigger cogs giving you better life from the cassette. With a 50, 51 or 52 tooth granny gear you’ll still have all the climbing power you’ll need. From...

UART is best for tuning. The 60 volt m620 is Canbus.

You can’t use a 60 volt battery on a 48 volt m620. The 1800 watt m620 has a custom controller to suit 60 volts. Can you order you bike with the 52 volt m620, if so I would go with that. Also do you know if you are getting the Canbus or UART version of the m620?
