Hi, I live on a hill. I guess you can consider it a mountain. I'm not intending to do any mountain biking in the conventional sense, and I know the Nireeka bike is not meant for that, meaning it is really not designed for "off-roading". That said, my hill is probably around a 15 degree grade, and lasts about two miles. Its about 25 minutes of "granny gear" climbing on my current bike. Its all paved but I will need to climb it at the end of every outing. I weigh 160 pounds. I have heard that this type of requirement is better served by a mid-drive motor. Is there a reason why the Nireeka design team chose a hub-drive motor, versus a mid-drive? Will the standard Nireeka Homie be able to handle my hill on a daily basis? Will the 500 W motor suffice? Would I be better served by the 1000 W motor?
I was looking into alternative ways of charging the battery/batteries as I was thinking about hiking in the outback with the Nireeka. I go for long drives so how nice would it be to then ride but the places I visit would not allow me to recharge easily. I will have a spare battery but how good would it be to somehow have a way of recharging. Been looking at solar panels and car power supplies so I can charge the battery while driving. Would love to know if any of you have experience in this area and how to best prepare for the Nireeka's arrival. It is only an idea for now but I am dreaming about riding around Australia on the Nireeka. That's almost 15,000 kms (over 9,000 miles) If I was to ride approximately 30km/h on average, that's 500 hours. If I ride 3 to 4 hours a day, it will take me 6 months including rest days and having fun. I can do this, its is not unreasonable. Charging the battery now that's a different story.
Hi Max, The following weight information has been gleaned from the Nireeka story: 250W motor = 4.2kg with 48Nm of torque (top speed of 15.5mph) 350W motor = 4.2kg with 48Nm of torque (top speed of 18mph) 500W motor = 4.2kg with 48Nm of torque (top speed of 20mph) 1,000W motor = 5.8kg with 85Nm of torque (top speed of 30mph) 36V, 7.2Ahr battery: ?.? lbs (?kg) 36V, 9.0Ahr battery: ?.? lbs (?kg) 36V, 10.8Ahr battery: 4.4 lbs ( 1.99kg) 48V, 14.4Ahr battery: 8.8 lbs (4kg) The reason for asking is to see what's the best weight/power combination suitable for each backer. For instance, with current information available, a 500W motor combined with the 36V, 10.8Ahr battery - has a total weight of 7.5kg (16.5 lbs) and 48Nm of torque. Top speed of 20mph on a straight run (don't know what assumptions are used to get this top speed). The 1,000W motor needs the 48V, 14.4Ahr battery. Battery weight is known, but details on 1,000W motor is still outstanding. Would like to have some clarification on the missing information. Thanks. Edit00: I've provided links for the 250W/350W/500W Bafang motors, but unsure if these are the model numbers that Max and N-Team are providing for backers. Some clarification would be useful. Edit01: Up-dated the 250W/350W/500W motor based on advise from Max and Younes from IGG. Edit02: Up-dates for 36V 10.8Ahr and 48V 14.4Ahr battery weights as advised by Max. Edit03: Up-date to 36V 10.8Ahr battery as per story on IGG.
