Hi I rode my HB3 first time today. I could use 1st speed at the beginning, but gear ratio doesn't change to 1st speed from some time. I can shift the lever and I can see fulcrum level moves to 1st speed yellow marker, but gear ratio remains to 2nd speed. What should I do?

any other Halfbikers in Toronto or the GTA!? we need a group to share Halfbike hacks, accessories (and their locations of acquirement), what are the best trails and locations to ride, and best ways to ride. Halfbikers Of Toronto Unit!!!

Last week I experienced the first time a cracking noise in 3rd gear, now when I stop pedaling and start again in 3rd gear, occasionally there is no traction. The yellow lines are matching perfectly in 2nd gear. Seems like there is a broken tooth inside the hub.

With the Covid lockdown, I’ve been trying to find a way to do indoor training with my HalfBike 2. I tried a Rexer Roller but it doesn’t work well - the balance is too hard and the wheel slips off too easily because of the shifting weight. Does anyone have any ideas for what might work?

Anyone tried changing from the current sturmey archer X-RD4 to 8 speed X-RD8? I love my bike, riding for a couple of weeks now and would like to experiments with higher gear ratio, I got some uphill passages on my treks that give me trouble. I also dont like the shifter that is present on X-RD4. Im not sure what specs should I be looking for to know if the 8 speed version would be compatible with HB3, can anyone chime in? https://www.sturmey-archer.com/en/products/detail/x-rd4 I was also thinking about Shimano Alfine/Nexus 8-11 speed hubs, but not sure if those would fit HB3. https://bike.shimano.com/en-EU/technologies/component/details/inter-8.html https://bike.shimano.com/en-EU/technologies/component/details/inter-11.html https://www.sturmey-archer.com/en/products/detail/x-rd8

I am selling a barely used Halfbike 3. I recently received an injury and can't use it any more. If you would like me to ship directly to you, I would be happy to. Or if you live in Pittsburgh I can deliver directly to you, or you can pick it up. $500 and any delivery fees.

Hi There - I am looking to buy a second hand half bike 3 and wondered if anyone has one for sale in the Uk? - Kemi

Hi, I would love to acquire a Halfbike 3 but customs fees to UK put it out of my price bracket. Does anyone in the UK have an as new as possible condition one they are looking to sell?

I live in Brisbane Australia and have been half biking for about 6 months and love it. Apart from the better workout it builds new skills in balance and strength. Keen to catch up with any other half bikers in Brisbane.

What is the right size of this nut? The one a got does not fit inside the black knob.

Hi, what is the exact length of the HB3 front wheel spokes in mm? Thanks in advance, Stefan

Halfbikeが故障して、ペダルを踏んでも空回りのようになります ギア部分が壊れているのかもしれません 修理は日本にある自転車屋さんに頼めばいいんでしょうか？ よろしくお願いします

Hi Halfbikers, This morning my bike got a big problem (hope not). I shot a short video about this. https://www.youtube.com/watch?v=7fwnMKwslOo You can see the chain is moving, but the wheel is not spinning. I hope i need only some adjustment for sturmey archer x-rd4 and this is not a breakdown.

I am in Utah and have been thinking about the 30 day trial program. What are the shipping costs I would have to pay in case I miserably fail at this? Thanks

With 12 months of use, my chain is becoming loose. I loosened the bolts yet the wheen doesn't move so that I can tighten the chain. How do I do this?
