Hi, I decided to get into the ebike world simply because at my age ,70, i really struggled to get up the local hills, so, also to avoid a heart attack ,i bought the Lo26 just before christmas . Heading nicely for 200 miles on the bike and really enjoying using it, can't complain about the build quality and love the design , with the battery storage especially theclever battery storage.Couple of questions if any other Lo26 users can help. Under load ,the motor sounds more noisy than it did originally , any ideas would be helpful. As i'm sure other users have found the total lack of backup is slightly worrying , but, i really do like the bike so any advice on where to source any parts i may need in the future , Thank's for any advice.







Tech wise

It's almost impossible to damage the motor in normal use. It should be good for 30,000 miles.

Motors make loud gear-type noises at low speed and high power when you have a crappy controller. What you're feeling/hearing is the commutation pulses, which you can discern at low speed. Once the motor speeds up, the pulse frequency is high enough that you can no longer hear/feel the gaps between them.

A sine wave controller will smooth out the pulses and make the motor nearly silent.

many thanks for your prompt and very helpful reply . Just to pick your brain a little more, When you mention a sine wave controller, is this an addition to the present controller or do i need to upgrade the exosting unit? Many thank's once again for taking the trouble to reply to my post

You replace your existing motor cotroller. In principle, they all controllers have the same main functions, use the same sensors and have the same wires. in practices, you have to do a bit of wiring and soldering to use a replacement controller.

We can give more specific advice if you show us your controller with all its wires and connectors spread out.
